So long ago I had the thought to just wrap a coil around a magnet, and thought why wouldn't the magnets magnetic field then create currents in the coil I had wrapped (like a reverse electromagnet). Me being naive at the time, didn't understand the magnetic field had to be moving or varying.

After spending lots of time reading up on what exactly makes the magnetic field of a magnet, I had a thought. If the electrons are moving and have electron spin, then the simple humble magnets magnetic field HAS to be moving to some degree. After lots of time messing with coils and magnets I kind of gave up on the subject for a while.

So today I had the thought to ask ChatGPT about this idea. At first it was just general answers explaining that the magnets magnetic field is not varying as a blanket statement to most of my questions, but after rewording I asked more carefully pointing out that the magnetic field is indeed being generated by MOVING electrons that the humble magnets magnetic field IS indeed in motion.

The next problem, is how much its varying and at what frequency.

Here's some of the conversation I had with ChatGPT just now about this.

"But because the electrons are moving and spinning one would think the magnetic field being created is then varying ever so slightly and probably at a very high frequency.

ChatGPT
You are correct that the motion and spin of electrons within a material can create a magnetic field, and that field may vary at a very small scale and at high frequencies. However, in the context of a permanent magnet, the overall magnetic field produced is relatively stable and does not vary significantly over time.

The motion and spin of electrons within an atom do create microscopic magnetic fields associated with each electron. These fields can have an inherent variation due to the quantum mechanical nature of electrons. However, in a macroscopic sense, the collective alignment of these electron spins in a permanent magnet creates a relatively static and uniform magnetic field.

The magnetic field of a permanent magnet is characterized by a steady and consistent arrangement of electron spins, resulting in a stable magnetic moment. This alignment persists in the absence of external influences, leading to a relatively constant magnetic field.

To generate a varying magnetic field for practical purposes like electricity generation through electromagnetic induction, an external influence is typically required. This can involve moving a magnet relative to a conductor, varying the current in a nearby coil of wire, or utilizing alternating current to induce changes in the magnetic field.

In summary, while the motion and spin of electrons within a magnet may contribute to a small-scale variation in the magnetic field, the overall magnetic field of a permanent magnet remains relatively stable and does not change significantly over time."

So if the magnetic field in a magnet is varying (how slightly shouldn't matter) because its high frequency couldn't one in theory create a coil that is tuned to the high frequency of this variation and produce a current in the coil.
ChatGPT
I apologize for any confusion caused by my previous responses. Let's address your new question.

In theory, if the magnetic field in a magnet were to vary at a high frequency, it is possible to create a coil tuned to that frequency and induce a current in the coil through electromagnetic induction.

However, it's important to note that in the case of a permanent magnet, the variation in the magnetic field due to the motion and spin of electrons is typically extremely small and occurs at very high frequencies. These variations are generally on the order of the material's atomic or molecular vibrations, which are typically in the terahertz (THz) or higher frequency range.

Creating a coil that can efficiently capture such high-frequency variations in the magnetic field is technically challenging. The coil's dimensions and the properties of the wire used need to be carefully designed and optimized to resonate at the desired frequency.

Moreover, capturing and utilizing the resulting current would require specialized circuitry and components capable of operating at such high frequencies. Designing and implementing practical systems to harness this kind of high-frequency magnetic field variation would be complex and require sophisticated engineering.

It's worth noting that in most practical applications, when generating electricity from magnets, electromagnetic induction is typically achieved by using relative motion between a magnet and a conductor or by utilizing changing magnetic fields produced by electrical currents in coils (such as in generators or transformers).

While the possibility of harnessing the high-frequency variations in the magnetic field of a permanent magnet exists in theory, it is currently not a common or practical method for generating usable electrical energy.

In theory, if the variations in the magnetic field of a magnet could be efficiently captured and converted into usable electrical energy, it could potentially become a valuable method for electricity generation. However, there are several challenges and considerations to keep in mind:

Extremely high frequency: The variations in the magnetic field of a magnet due to the motion and spin of electrons typically occur at very high frequencies, often in the terahertz or higher range. Capturing and utilizing such high-frequency variations would require specialized components and circuitry capable of handling these frequencies.

Efficiency and power output: The efficiency of the energy conversion process would be a significant factor. Converting small and high-frequency variations in the magnetic field into usable electrical energy with high efficiency can be challenging. It would require careful design and optimization of the coil, circuitry, and overall system to maximize power output.

Practical implementation: Designing, building, and maintaining systems capable of harnessing high-frequency magnetic field variations would require advanced engineering techniques and specialized materials. Moreover, the resulting system should be scalable, reliable, and cost-effective for practical deployment.

Energy density: The energy density of the magnetic field variations in a magnet is typically quite low. To extract a significant amount of electrical energy, one would need to find a way to magnify or amplify these variations to achieve useful power levels.

While it is intriguing to explore alternative methods for electricity generation, at present, more conventional approaches such as electromagnetic induction using relative motion or alternating current are widely used due to their practicality, efficiency, and scalability. However, ongoing research and technological advancements may lead to breakthroughs that could make harnessing high-frequency variations in the magnetic field of a magnet more viable in the future.

So in conclusion, and I have no idea if this is ever possible yet. Couldn't we design an inductor that is tuned to the frequency of a specifics magnets magnetic field high frequency. But as ChatGPT pointed out it would be in the "terahertz or higher range".

Anyone here smarter than me know if its possible to make an inductor thats tuned to the terahertz range? I'm still relatively new to understanding how to tune inductors or coils.

 JUST A ARTICLE.

So still at it with asking ChatGPT Questions... I recently came across a TikTok of all things talking about using Piezoelectric materials to generate electricity. I even bough some cheap transducers to mess with for experimentations sake, not much of a result, but I ordered a slightly larger one to further test with when I get it.

Anyways here's the end result of a conversation I had with Chat GPT today.

Yes, it is possible to generate electricity using a piezoelectric transducer without the magnets or magnetic fields moving. This can be achieved by using a different approach called the "magnetostrictive-piezoelectric" energy harvesting technique. In this method, the piezoelectric transducer is coupled with a magnetostrictive material to generate electrical energy.

Here's how it works:

Piezoelectric Transducer: As mentioned earlier, the piezoelectric transducer is a material that generates an electric charge when subjected to mechanical stress or strain.

Magnetostrictive Material: A magnetostrictive material is a substance that changes its shape when exposed to a magnetic field. This deformation occurs due to the coupling between the material's magnetic properties and its mechanical properties.

Permanent Magnets: In this setup, you will use fixed or stationary permanent magnets to provide a constant magnetic field across the magnetostrictive material and the piezoelectric transducer.

Coupling: The magnetostrictive material and the piezoelectric transducer are mechanically coupled together. When the magnetic field from the permanent magnets interacts with the magnetostrictive material, it causes the magnetostrictive material to change its shape. This, in turn, mechanically stresses the piezoelectric transducer.

Piezoelectric Effect: Due to the mechanical stress from the magnetostrictive material, the piezoelectric transducer generates an electric charge.

Electricity Generation: The electric charge produced by the piezoelectric transducer is then collected and stored or used to power electronic devices.

In this configuration, the magnetic field remains static, and electricity is generated by converting the magnetic energy into mechanical energy using the magnetostrictive material, and then further converting it into electrical energy through the piezoelectric effect.

This method can be useful in applications where a continuous magnetic field is present, such as in certain industrial processes or electronic devices that utilize permanent magnets. However, it's essential to consider the efficiency and practical limitations of this energy harvesting technique, as the power output might still be relatively low compared to more conventional energy sources.

So chatgpt say's its possible but might not be a huge power output. My next idea is to ask about things related to this while using resonance, like some how getting a transducer that resonates with the magnetostrictive materials, or even with the magnetic fields Terahertz level resonance.

Ok so according to ChatGPT this should in theory be possible. In fact its already been done. You use a good Piezoelectric material such as lead zirconate titanate (PZT).

The next step is to choose a really good "Magnetostrictive material"

Magnetostrictive Materials.

Terfenol-D (Terbium Dysprosium Iron Alloy)

Iron-Cobalt (Fe-Co) Alloys

Nickel-Iron (Ni-Fe) Alloys

Ferrites

Terfenol-D and Galfenol according to Chat GPT would be best suited for this situation. Unfortunately those metals aren't exactly stable and are not available to average consumers like myself.

Instead I'm thinking of trying to get my hands on some Iron-Colbalt or Nickel Iron.

The next part is the Magnetostrictive material chosen has to be carefully "Coupled" with the Transducer so the deformations of the Magnetostrictive material bend and move the Transducer. According to Chat GPT Magnetostrictive materials will deform constantly under a static magnetic field causing constant small changes to the Transducer if coupled together carefully with the right materials.


The next part which I am very excited about is something that as far as ChatGPT knows hasn't been tried by anyone as of 2021 as far as the information goes that the AI's been fed.

The idea is to take the electrical charge being formed in the transducer and redirect that into a Coil that's wrapped around the magnet creating the stationary magnetic field. This would make the magnetic field increase as the coil would act like a electromagnet around the magnet. This would increase the magnetic field that is being applied to the Magnetostrictive materials.

As it turns out the stronger the magnetic field is the greater the deformation of the magnetostrictive material there is. Which would then create even more electrical output from the transducer.

This would create a feedback loop that would continue to become greater and greater as the coil feeds more magnetic field into the system and more electrical output is generated. This would continue until either magnetostrictive material fails or some other part of the circuit burns up.

The feedback loop could be controlled if the Coil was free to slide over the magnet and slid off the magnet as needed to control the feedback loop.

I asked Chat GPT if this has ever been done, and as of 2021 it was not aware of such an idea or configuration being tried, but did say it should work in theory.

Now why am I posting this rather than testing it myself? I don't have access to much like I used to. I no longer live and home and don't have access to much in terms of tools and materials. I am however going to try and get my hands on some Iron-Cobalt (Fe-Co) Alloys or Nickel-Iron (Ni-Fe) Alloys and super glue it to some transducers and see what happens when I apply magnetic fields.

 :thumbsup:

I'm hoping someone here with better equipment can maybe help out with trying some of this. In my mind I don't see why it wouldn't work all the theories are sound.


Also if anyone's interested. Be warned its very long but heres the link to the ChatGPT conversation I had so far.
