Question
magnitude of torque
AB1
A rectangular loop consists of 124 closely wrapped turns and has dimensions 0.400 m by 0.300 m. The loop is hinged along the y-axis, and the plane of the coil makes an angle of 30.0degree with the x-axis (see figure below). What is the magnitude of the torque exerted on the loop by a uniform magnetic field of 0.808 T directed along the x-axis when the current in the windings has a value of 1.20 A in the direction shown? N middot m What is the expected direction of rotation of the loop? clockwise as viewed from above counterclockwise as viewed from the above The magnitude is zero.
Explanation / Answer
clockwise as viewed from above
