A bar magnet is positioned near a solenoid (coil of wire). In which of the following situations will an electromotive force (e.m.f.) not be induced in the solenoid?
Moving both the solenoid and the magnet towards each other, each at a constant speed of 2 m/s2\text{ m/s}2 m/s.
Moving both the solenoid and the magnet in the same direction, each at a constant speed of 3 m/s3\text{ m/s}3 m/s.
Keeping the solenoid completely stationary while moving the magnet away from it at a constant speed of 5 m/s5\text{ m/s}5 m/s.
Keeping the magnet completely stationary while moving the solenoid away from it at a constant speed of 4 m/s4\text{ m/s}4 m/s.
