A copper ring is dropped vertically downwards through a horizontal magnetic field. As the ring enters the magnetic field, an induced current is set up in it. This induced current interacts with the magnetic field to produce a force on the ring. In which direction is this force?
in the direction of the gravitational pull (downwards)
in the direction of the magnetic field lines
in the opposite direction to the magnetic field lines
in the opposite direction to the movement of the ring (upwards)
