A rigid square loop of side length $l$ carrying an electric current is held motionless on a frictionless horizontal tabletop. A uniform magnetic field pointing upwards is switched on everywhere to the left of the dashed line as shown in the figure and then the loop is released. Considering different lengths of the side segments x and y (x < y), which of the following conclusions can you make?

If $x < \frac{l}{2}$ and $y = \frac{l}{2}$ , the loop starts rotating anticlockwise.

If $x < \frac{l}{2}$ and $y > \frac{l}{2}$ , the loop starts rotating clockwise.

If $x < \frac{l}{2}$ and $y > \frac{l}{2}$ , more information is required to decide which way the loop starts rotating.

If $y < \frac{l}{2}$ and $x < \frac{l}{2}$ , the loop starts rotating anticlockwise.

answer is A, B, D.
