An electric generator consists of a circular coil of wire of radius 1.0×10−2 m , with 20 turns. The coil is located between the poles of a permanent magnet in a uniform magnetic field, of magnitude 4.0×10−2 T . The B field is orientated perpendicular to the axis of rotation. The ends of the coil are connected via sliding contacts across a resistor of resistance 1.5 Ω. The peak current measured through the resistor is 1.0×10−3 A
What is the angular frequency ω at which the coil is rotating? in rad/s to two sig figs
