Most of the electric motors we see these days are of the electromagnetic variety, and for good reason: they’re powerful. But there’s a type of motor that was invented before the ...

The introduction to this section explains how electromagnets function in telegraphs and telephones. Here are a few more examples: Inside an electric motor, current flows into a coil of wire ...

Traditional electric motors often rely on permanent magnets ... this motor employs contactless technology to energize its electromagnets. This innovative approach eliminates wear-prone components ...

That means we can transmit energy great distances in its electrical form and ... energy is caused by the attractive force of the electromagnet. Now imagine a circle of electromagnets that you ...

If the conductor is part of an electric circuit ... a simple experiment to demonstrate electromagnetic induction. The direction of a motor effect force can be found using Fleming’s left hand ...

Synchros are electromagnetic devices similar to transformers, where a set of windings induces a voltage on another set, but they also have a movable rotor like an electric motor. When the rotor is ...

The questions in this quiz are suitable for GCSE combined science students studying electromagnets, the motor effect, Fleming’s left hand rule, and electric motors. If you struggled with the ...
