Question

By reversing the direction of the current in an electromagnet, the magnetic field produced by it:

विकल्प

• increases in strength

• remains unchanged in strength and direction

• gets reversed in direction

• decreases in strength

Answer 1

Gets reversed in direction

Explanation:

Reversing the current reverses the direction of the magnetic field, so the north and south poles of the electromagnet get interchanged. Its strength depends on the amount of current and the number of turns, not on the direction of the current.
