The expression for the torque on a current loop was derived assuming that the magnetic field was uniform. But what if B→ is not uniform? The figure shows a square loop of wire that lies in the xy-plane. The loop has corners at (0,0),(0,L),(L,0), and (L,L) and carries a constant current I in the clockwise direction. The magnetic field has no z-component but has both x- and y-components: B→ =(B0y/L)i^+(B0x/L)j^, where B0 is a positive constant.
Part A
If the loop is free to rotate about the x-axis, find the magnitude of the magnetic torque on the loop.
Part B
If the loop is free to rotate about the x-axis, find the direction of the magnetic torque on the loop.
If the loop is free to rotate about the y-axis, find the direction of the magnetic torque on the loop.
Part C
If the loop is free to rotate about the y-axis, find the magnitude of the magnetic torque on the loop.
Part D
If the loop is free to rotate about the y-axis, find the direction of the magnetic torque on the loop.
If the loop is free to rotate about the x-axis, find the direction of the magnetic torque on the loop.
