Question

If the needle in the galvanometer is going up, what can you conclude about the motion of the magnet in the diagram?

It must be moving left.

It is not moving.

It must be moving right.

It is being moved in an unknown direction.

Answer 1

Thank you for coming to help

Answer 2

The current acts in such a way to oppose the CHANGE in the external magnetic field. Since the current is going up on the right, this means that the induced magnetic field of the coil is to the right. This means that the external field is moving to the left since the current is in such a direction to oppose this motion.

Does this make sense?

Answer 3

Total sense thank you again.
