A bar magnet falls vertically through a magnet. Its acceleration is

• less than g

• more than g

• equal to g

• zero

A bar magnet is moved along the axis of a copper ring placed far away from the magnet. Looking from the side of the magnet an anticlockwise current is found to be induced in the ring. In this situation

• the S-pole faces the ring and the magnet moves towards it

• the N-pole faces the ring and the magnet moves towards it

• the S-pole faces the ring and the magnet moves away from it

• the N-pole faces the ring and the magnet moves away from it.
