Experiments suggest an unusual magnetic material could help harness energy from Earth’s rotation. But not everyone is ...

But, there may be another way, albeit a rather special case, where a magnet can not only be levitated, but locked in place using a rotating magnetic field. The video shows a demonstration of how ...

The problems associated with rare and difficult-to-obtain materials – as used in motors that power EVs as well as batteries – ...

Just like rotating a shaft with magnets on it could. The secondary converts that alternating magnetic field into electricity just like a generator does. In other words, a transformer is just a ...

Slip rings maintain constant contact with the same sides of the coil As one side of the coil moves up through the magnetic field, a potential difference is induced (created) in one direction.

It shows four different positions of the coil of the generator, and the corresponding induced current. A - The coil is at 0°. The coil is moving parallel to the direction of the magnetic field ...
