Question

A bar magnet is oriented above a copper ring, with the south pole downwards. If the magnet is pulled upward, what is the direction of the current induced in the ring, as viewed from above?

Answer 1

The current induced in the copper ring, as viewed from above, when a bar magnet with its south pole facing downward is pulled upward is clockwise.

Step-by-step explanation:

The direction of the current induced in the copper ring, as viewed from above, when a bar magnet with its south pole facing downward is pulled upward is clockwise.

This can be determined by using the Right-Hand Rule. When the magnet is pulled upward, the flux through the ring is decreasing. To oppose this change, a current is induced in the ring that creates a magnetic field with north pole facing downward, which repels the south pole of the magnet. By using the Right-Hand Rule, it can be concluded that the direction of the induced current is clockwise.

It is important to note that when the north pole of the magnet is moved towards the copper loop, the direction of the induced current is also clockwise.
