An equilateral triangular loop is kept near to a current carrying long wire as shown in figure. Under the action of magnetic force alone, the loop


must move along positive or negative X-axis
must move in XY plane and not along X- of Y- axis
does not move
moves but which way we cannot predict
Verified by Toppr

The magnetic field would be into the plane of the triangle, with magnitude decreasing as gone farther from the the current carrying wire. From symmetry, the magnitudes of F1 and F2 would be same. Thus they would not have any vertical component.
Thus, the triangle would move only in the X-direction.
