How is the role of an electromagnet in a motor different from the role of an electromagnet in an generator?
I thinkit is different because a motor changes eletricalenergryinto motion a generator changesa motion into eletericalenergy.
Why electromagnet is different from a permanent magnet because an electromagnet what?
Mainly in that the electromagnet is NOT permanent. In other words, it can be switched on and off.Another relevant difference is that the electromagnet constantly requires power, at least while it is on.
How an electromagnet is useful in a different ways?
All electric motors are electromagnets.
How do make an electromagnet stop working?
An electromagnet is powered by electrical current and that current can be adjusted to different levels of magnetism,Êso if you disable its electrical connection it will not work.
How is an electromagnet different from a refrigerator magnet?
A refrigerator magnet is magnetic because it is a "permanent" magnet. An electromagnet is a magnetic field caused by a current flowing through a wire.
Is a refrigerator magnet electromagnetic?
IT is different because an electromagnet runs with electricity. A refrigiator does not run with electricity.
How is electromagnet different from a regular bar or horseshoe magnet?
It requires a current through a coil of wires.
Which is better a permanent magnet or an electromagnet?
electromagnet
Strong temporary magnet formed when a current is passed through a coil of wire?
A magnetic field.
