Question

A magnet makes a single pass through a coil for the ends of the coil it produces

Answer 1

If a magnet makes a single pass through the coil it produces a magnetic flux.

• Any induced current in a coil will result in a magnetic flux opposite to the original flux which changes.
• The induced current generates a north pole, pointing to the north pole of the magnet, into the conducting loop.
• This creates a repulsive force which opposes the change which has caused the current.
