Question

what is an electromagnet?what are its properties​

Answer 1

A soft metal core made into a magnet by the passage of electric current through a coil surrounding it is called electromagnet.

The main properties of an Electromagnet are:

(i) An electromagnet is temporary in nature.

(ii) An electromagnet is made of a soft iron core.

(iii) The magnetic field strength can be changed

(iv) An electromagnet can be easily demagnetized by switching off the current.

(v) The polarity can be reversed.

Answer 2

Answer:

A magnet formed temporarily due to magnetic field of a current is called an electromagnet.

Explanation:

Electromagnet have the following properties:-

1. on like a permanent magnet the electromagnets magnetism is not permanent.

1. The electromagnet has pole at its end. However , the end at which a pole appears is not fixed. Thepolls get interchange when the direction of current through the solenoid is changed.

the iron used nails bolts acceptor is a soft magnetic material. search a material becomes magnetized in a magnetic field but loses its magnetism once the field is removed.
