A 50 turn square coil has an area 10.0 cm^2 and is rotated with an angular speed of 190.0 rad/s in a uniform 0.90 T magnetic field.
a) If the coil forms a closed circuit with a series resistance of 70.0 ?, what is the instantaneous power being dissipated in the resistor when the plane of the coil makes an angle of 39.0° with the magnetic field?
