Question

When a wire moves through a magnetic field, an electric current is produced in the wire. Why does this phenomenon occur?

Answer 1

It occurs whenever a magnetic field and an electric conductor move relative to one another so the conductor crosses lines of force in the magnetic field.

Answer 2

It occurs whenever a magnetic field and an electric conductor move relative to one another so the conductor crosses lines of force in the magnetic field.

Step-by-step explanation:

The current produced by electromagnetic induction is greater when the magnet or coil moves faster, the coil has more turns, or the magnet is stronger.
