Question

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

Answer 1

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.

Answer 2

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.
