Question

A conducting loop is located in a magnetic field B directed out of the screen and perpendicular to the loop. The magnitude of the field is increasing,what will occur in the conducting loop

Answer 1

Answer:

  current is induced in the loop in the clockwise direction

Explanation:

The right-hand rule can be used to find the direction of the field created by a current flowing in a loop. When the fingers point in the current's direction, the thumb points in the direction of the field created.

Here, the current induced in the loop creates a field that opposes the change in the externally applied field. If the external field is increasing out of the screen, the current induced in the loop will create a field in the direction into the screen, opposing the change. Hence the induced current will flow clockwise around the loop.
