A simple DC motor consists of a single coil of 100 loops, rotating in a magnetic field with flux density B = 170 mT. The area of the coil is 3.50 × 10–4 m2. When the angle between the plane of the coil and the magnetic field increases from 15.0° to 45.0° the torque on the coil decreases by 5.39 × 10–3 N m. Calculate the current flowing through the coil.
