A wire is looped into a circle of radius “R” and carries a current “i”. The magnetic dipole moment is now found to be “M”. Then

$\overline{M}$ is parallel to plane of loop

$\overline{M}$ parallel to current ‘i’

$\overline{M}$ is perpendicular to plane of loop

$\overline{M}$ may be parallel (or) perpendicular to loop
