Multiple Choice
A bar magnet is suspended above a coil of wire by means of a spring. The ends of the coil are connected to a sensitive high resistance voltmeter. The bar magnet is pulled down so that its north pole is level with the top of the coil.
The magnet is released and the variation with time t of the velocity v of the magnet is shown.
Which point (s) in the motion shows when the reading of the voltmeter will be at maximum ?

Multiple Choice
A uniform magnetic field of strength B completely links a coil of area S. The field makes an angle Φ to the plane of the coil.
The magnetic flux linking the coil is

Multiple Choice
The north pole of a permanent bar magnet is pushed along the axis of a coil as shown. The pointer of the sensitive voltmeter connected to the coil moves to the right and vies a maximum reading of 8 units.
The experiment is repeated but on this occasion, the south pole of the magnet enters the coil at twice the previous speed.
Which of the following gives the maximum deflection of the pointer of the voltmeter?
