A long solenoid has 1400 turns per meter of length, and it carries a current of 2.0 A. A small circular coil of wire is placed inside the solenoid with the normal to the coil oriented at an angle of 90.0˚ with respect to the axis of the solenoid. The coil consists of 46 turns, has an area of 1.2 × 10-3 m2, and carries a current of 0.75 A. Find the torque exerted on the coil.
