The diagram shows a vertical square coil whose plane is at right angles to a horizontal uniform
magnetic field B. A current, I, is passed through the coil, which is free to rotate about a vertical
axis OO'.
Which one of the following statements is correct?
A
The forces on the two vertical sides of the coil are equal and opposite.
B
A couple acts on the coil.
C
No forces act on the horizontal sides of the coil.
D
If the coil is turned through a small angle about OO' and released, it will remain in position.
