In a region of uniform magnetic induction B=10^(2) tesla, a circular coil of radius 30 cm and resistance pi^(2) ohm is rotated about an axis which is perpendicular to the directon of B and which form a diameter of the coil. If the coil rotates at 200rpm the amplitude of the alternating current induced in the coil is

In a region of uniform magnetic inductance B=10^(-2) tesla. A circular coil of radius 30 cm and resistance pi^(2) ohm is rotated about an axis which is perpendicular to the direction of B and which forms a dimater of the coil. If the coil rotates at 200 r.p.m the amplitude of the alternatic current induced in the coil is

A cylindrical bar magnet is kept along the axis of a circular coil. If the magnet is rotated about the axis, will there be any current induced in that coil?

A square coil of side 25cm having 1000 turns is rotated with a uniform speed in a magnetic field about axis perpendicular to the direction of the field. At an instant t , the e.m.f. induced in the coil is e=200 sin 100pi t . The magnetic induction is
