Interaction of a Current Loop with a Magnetic Field

The effects due to the interaction of a current-carrying loop with a magnetic field have many applications, some as common as the electric motor. This problem illustrates the basic principles of this interaction.

Part B

Assume that the loop is initially positioned at =30and the current flowing into the loop is 0.500 A . If the magnitude of the magnetic field is 0.300 T , what is , the net torque about the vertical axis of the current loop due to the interaction of the current with the magnetic field?

Explanation / Answer

torque = IBASin(theta)

torque = (0.5*0.3*0.04)sin(90-30)

torque = 0.000104 N*m
