A 200-turn rectangular coil having dimensions of 3.0 cm by 5.0 cm placed in a uniform magnetic field of magnitude 0.90T.
(a) Find the current in the coil if the maximum torque exerted on it by the magnetic field is 0.15 N.m
(b) Find the magnitude of the torque on the coil when the magnetic field makes an angle of 25 degrees with the normal to the plane of the coil.
