(a) How would you demonstrate that a momentary current can be obtained by the suitable use of a magnet, a coil of wire and a galvanometer?

(b) What is the source of energy associated with the current obtained in part (a)?

State Fleming's right hand rule.

Why does it become more difficult to move a magnet towards a coil when the number of turns in the coil has been increased?

Explain why an induced current must flow in such a direction so as to oppose the change producing it.
