A 175 turn rectangular coil having dimensions of 2.9 cm by 5.1 cm is placed in a uniform magnetic field of magnitude 0.85 T.
(a) Find the current in the coil if the maximum torque exerted on it by the magnetic field is 0.18 N · m.
(b) Find the magnitude of the torque on the coil when the magnetic field makes an angle of 27° with the normal to the plane of the coil. N x m
