Explanation :

An electromagnet has a coil of wire which is wrapped around an iron core. When an electric current is passed over it, it behaves like a magnet.

For DC current,

When the direction of current is reversed in an electromagnet, its poles gets reversed.

For AC current,

AC or alternating current continuously changes the direction of the current. So, the north poles and south poles keep on changing.

So, the north and south poles of a magnetic field produced by an electromagnet will switch when the direction of the current changes.

If we reverse the direction of the current, the north and the south poles of the electromagnet will become reversed.

What is an electromagnet?

An electromagnet is a magnet that derives its magnetic properties from being exposed to an electric field. We know that the poles of an electromagnet depends on the current.

Now, if we reverse the direction of the current, the north and the south poles of the electromagnet will become reversed.
