Question

The direction of the magnetic dipole moment of a current loop is:

Options

• Perpendicular to the plane of the loop

• Along the plane of the loop

• Along the axis, but only at the centre of the loop

• Tangential to the loop at every point

Answer 1

The magnetic moment \(\vec{m}\) of a current loop is directed perpendicular to the plane of the loop, with its sense given by the Right-Hand Thumb Rule applied to the conventional current.
