Sorry, 50mm diameter would be more realistic for a hobbyist.

Thanks for the replies! I'm putting a day aside to read the link Jim, thanks for that. (got 4yo twins, so time's a premium) I've been constantly frustrated in my thought experiments by coils. Is there a ready reckoner that can tell you the ideal gauge, number of windings, distance from magnet...

Hi russ_waters, I'm not actually planning to connect anything to the grid, whether it be an electric drill or any other device, if I WERE planning to do so I wouldn't come to the PF and ask questions about running an electric drill backwards, I would go to relevant website re the subject and I...

Thanks for the reply, Now for a HUGELY moronic question. If we were to take the fabled drill and plug it into the living room wall in the normal way, then turn the bit externally, would the electricity generated go back into the grid (via its connection on the living room wall), either...

The hand drill was just an example of something that has an interface (the bit) that would allow for external rotation of the internal rotor, thus making it a handy tool for discussing 'reverse' generation. You'd need a few to make your morning toast! if you hooked it up (via all the necessary...

Hi, If you turn the bit in an electric drill will it generate electricity? What would you need to do for it to produce enough electricity to feed back into the grid?

So, 10 magnets with 9 independent coils would have 90 coils generating a current per turn, whereas 10/10 would have 100 coils generating a current per turn. Both would be AC (?). You say "If 10 magnets and 10 coils then coils can be in series, each then needs to produce less voltage, so it can...

What if there were 10 magnets, and 10 independent coils?

What if each coil was separate.

So it wouldn't produce a charge? If the electrons in the wire are excited, then surely a voltage is produced?

Hi, Why won't a generator composed of a stator that has 9 coils (each connected to it's neighbour in a ring until line out), and a rotor that has 10 permanent n50 magnets (NSNS...) generate useable electricity?
