Question

Suppose an induced current aided the flux change as an N-pole approached a coil. Which pole would form on the near face?

Options

• A North pole that repels the incoming North pole

• No magnetic pole because flux is changing

• A South pole that attracts the incoming North pole

• A North pole that attracts the incoming North pole

Answer 1

If the induced current aided the change rather than opposing it, the near face would become a South pole. It would attract the approaching N-pole instead of resisting its motion.
