Please show all steps! Thank you! (#17)

A 20-turn 50. cm by coil hangs with the plane of the coil parallel to a 0.12-T magnetic field. (a) Determine the torque on the coil when there is a 0.50. A current through it. (b) The support for the coil exerts an opposing torque, which increases as the coil is deflected. The opposing torque is calculated using the equation tau = -0.016 theta (in units of N m), with the angle theta in units of radians. At approximately what angle does the magnetic torque balance the torque balance the torque caused by the supporting wire? An electric motor has a circular armature with 250 turns of radius 5.0 cm through which and 8.0-A

Explanation / Answer

torque=0.3N-m

theta =2.98
