Travel in the other direction as the magnetic field moves away from the wire

Answer 1

The three configurations in which induction takes place are: when the magnetic field is approaching the wire, when the magnetic field moves away from the wire, and when a steady strength, moving, magnetic field crosses a stationary wire.

Step-by-step explanation:

1. Travel in one direction when the magnetic field is approaching the wire: This configuration is known as the Faraday's Law of electromagnetic induction. According to this law, when a magnetic field is approaching a wire, an induced current is created in the wire in such a way that it opposes the change that is causing it.
2. Travel in the other direction as the magnetic field moves away from the wire: This is also a configuration of Faraday's Law. When a magnetic field moves away from a wire, an induced current is generated in the wire, but in the opposite direction as compared to the previous configuration.
3. A steady strength, moving, magnetic field crosses a stationary wire: This configuration is known as the generator. When a wire is placed perpendicular to a moving magnetic field, an induced current is produced in the wire.
