Starship, Rodin and other electromagnet designs
« on April 4th, 2012, 12:44 PM »
Hello to all!! I hope to be around a while soaking up information.

Reason for thread
So after about 3 months of; researching, dead ends, and hours of youtube demonstrations, I've come here to learn from people much more experienced than I.

My Application
I am trying to build a coil with a 2 inch diameter. I want it to produce a 1.4T field in it's center. The coil can only be 1/2 an thick. I will then make a core out of 99.95% iron wire and epoxy.  I am basically trying to make an electromagnet with it a core  equal in size and strength as a 2x1x1 inch N42 bar magnet.

My Questions
What I can't figure out is how to calculate the b-field of a starship coil. On top of that, I can't decide on which type of coil will produce the strongest field at limited thickness.

I haven't been able to find out why a starship type coil produces a stronger magnetic field than a traditional electromagnet. Does anyone know the answers to these questions or have a link they could share?

Russ or Firepinto could probably help you.

my tests /theory has shown that these coils produce such a magnetic field that the field is not contained but instead reflected out!

so the wire crossing in a 90 degree from each other dose some weird things like project the magnetic field instead on making it all concentrated...

i hope this makes sense.

look up what happens when 2 wires are 90 degrees from each other.

i'm not sure how much T my coils produce as i don't have a way of checking. but i can these babys put off a tun of emf... that's bad for your health if over exposed. i have gotten sick from a lot of power pumped in to this coil:

i hope this helps. one place i can recamend you is here:

be sure to join the rodincoil group on Google...  

also skycollection on youtube is doing some really cool stuff...

Thank you for the links. Lots of new and interesting topics to read. As for skycollection, I believe I have watched everyone of his videos. He is one of the only people I know of using a core in a starship.

What do you think about using aluminum versus copper in a starship coil? I'd like to think the aluminum's paramagnetic characteristic would aid in magnetism.
