Question

The direction of the magnetic field produced by an electric current will change when the direction of the _ changes.

Answer 1

Electromagnetism is the magnetism produced by an electric current.A wire carrying an electric current produces a magnetic field.The direction of the magnetic field produced by an electric current will change when the direction of the current changes.

Answer 2

Answer: Electric current

Explanation :

The direction of the magnetic field produced by an electric current will change when the direction of the electric current changes.

For example :

If a current is flowing in a straight length of wire, the magnetic field is described by a concentric circle (using right-hand rule).

Let the field lines are in the clockwise direction and when the direction of current is reversed then the direction of the magnetic field is in anticlockwise direction.
