Question
A rectangular loop consists of 125 closely wrapped turns andhas dimensions 0.40m by 0.30m. The loop is hinged along the y-axisand the plan of the coil makes an angle of 30 degrees with thex-axis. What is the magnitude of the torque exerted on the loop bya uniform magnetic field of 0.728T directed along the x-axis whenthe current in the windings has a value of 1.2A in the directionshown? *picture in book* What is the expected direction of rotationof the loop? This is realy complicated, will rate good! A rectangular loop consists of 125 closely wrapped turns andhas dimensions 0.40m by 0.30m.

This is realy complicated, will rate good!Explanation / Answer
torque = BIANsin(theta)
torque = (.728T)(1.2A)(.12 square m)(125 turns)sin(theta) =13.104sin(theta)
T=13.104*sin60=11.348
