358612 A coil has 1,000 turns and \(500\;c{m^2}\) as its area. The plane of the coil is placed at right angles to a magnetic induction field of \(2 \times {10^{ - 5}}\;Wb/{m^2}\). The coil is rotated through \(180^{\circ}\) in 0.2 seconds. The average emf induced in the coil, in milli volts, is:

1 5
2 10
3 15
4 20
PHXII06:ELECTROMAGNETIC INDUCTION

358613 Whenever a magnet is moved either towards or away from a conducting coil, an emf is induced, the magnitude of emf is independent of

1 The speed with which the magnet is moved
2 The number of turns of the coil
3 The area of cross-section of the coil
4 The resistance of the coil
