A bar magnet is pushed north pole first into a solenoid that is part of a complete circuit. Which statement about the induced magnetic field or current is correct?
The induced current creates a magnetic field with a south pole at the end of the solenoid nearest to the magnet, to attract the incoming north pole.
The induced current creates a magnetic field with a north pole at the end of the solenoid nearest to the magnet, to repel the incoming north pole.
The direction of the induced current is always in the same direction as the motion of the magnet.
The magnitude of the induced current is independent of the speed at which the magnet is moved.
