Hi
This is your answer.
Properties of an electromagnet are.
1. The strength of the electromagnet is stronger than a permanent magnet.
2. It's strength do not deteriorate in course of time as permanent magnet.
3. It's strength can be decreased or increased by changing the current in solenoid.
4. It's polarity can also be changed by reversing the direction of the current.
5. Electromagnet are used in all kinds of electric devices, including hard disk drives, speakers, motors, and generators, as well as in scrap yards to pick up heavy scrap metal.

Property of Electromagnets
1. Electromagnets are very strong temporary magnets when the currents is passed through them and get demagnetized as soon as the current is switched off.
2. The strength of electromagnet depends upon the current in the coil and it also depends upon the type of bar used.
3. These magnets can be made in different size and shapes depending on their use.
Strength of electromagnets depends upon the following factors :-
1. The number of turns of copper wire wound on the soft iron bar or iron needle.
2. The strength of current flowing through the wire.
