A student has a coil of wire, a bar magnet and a centre-zero ammeter.
The coil is connected to the ammeter.
Describe how the student can use this apparatus to induce a current in the coil.
The student holds the magnet still inside the coil.
State the reading on the ammeter.
Give a reason for your answer.
