Totally awesome learning    Thanks
I've been wondering about permanent magnets in all sorts of devices ....
Is the power of magnetic decreasing by time ?
If yes, is it relative to what kind, or amount, of energy you get from such devices ?

Nothing last forever but magnets last longer than humans. Look online for how long but I assume it depends on the magnet.

Things are learned over time. Some feel it is best to be a master of one thing but miss out of other things, and others feel its better to be a jack of all trade to understand more things which might interact with each other, but miss out knowing a single topic well. Life is short.

I think a magnet motor alone wont work without the help of a electromagnet giving it a boost to pass the hump with the help of an external energy source.

How the US navy in 1954 explained how magnets work "How Magnets Produce Electricity Electromagnetism Prime"

Sometimes one has to take a step back and see the basics for a warm up. It could be at times to take one step back two steps forward.
