Asquare current loop 4.5cm on each side carries a 460ma current. the loop is in a 1.2t uniform magnetic field. the axis of the loop, perpendicular to the plane of the loop, is 30? away from the field direction.

what is the magnitude of the torque on the current loop?

How does a circuit breaker protect a refrigerator? a. when the current is too high, a metal strip in the fuse melts and opens the circuit. b. when the resistance is too high , a re-settable which opens a circuit c. when the current is too high , a re-settable switch opens the circuit d. when the resistance is too high a metal strip in the fuse melts and opens the circuit
