Question

In the system illustrated by the diagram, the magnetic field is increasing. In which direction is the induced emf, if any?

A. It is moving clockwise.

B. It is moving counterclockwise.

C. The induced emf is zero.

Answer 1

it is clockwise, since the induced current generates a magnetic flux which balances the increased external magnetic flux

Answer 2

ohh okay! thanks!!:)

Answer 3

here, in order to establish the orientation of the current is necessary to apply the right hand rule

Answer 4
