Question

When the N-pole moves away from the coil, which induced current direction and near-face pole are observed?

Options

• No current; no pole on the face of the coil

• Anticlockwise viewed from the magnet; North pole that repels the magnet

• Clockwise viewed from the magnet; South pole that attracts the magnet

• Clockwise viewed from the magnet; North pole that repels the magnet

Answer 1

The receding N-pole produces a clockwise induced current when viewed from the magnet. The near face becomes a South pole, attracting the magnet and opposing its motion away.
