the polarity gets reversed
TheStraightCstudent:
Care to explain why?
it is an advantage of electromagnet and the direction is reversed so polarity can be changed by reversing direction of current

It is a temporary magnet powered by electricity Wire is coiled around an iron core and the ends of the wire are connected to a battery. When electric current passes through it, it magnetizes the metal core.
It you reverse the terminals of the battery, the direction of current is also reversed. The reason is that, when the direction of the current is changed, the north and south poles of the electromagnet are also reversed. In case of direct current (DC), the change in the polarity occurs once whereas in alternating current (AC), the direction of current is constantly changing, so north and south poles will also change continuously.
Hope it will help you. Thanks.
