Q. A current loop in a magnetic field :

Can be in equilibrium in two orientations, one stable while the other is unstable.

Experiences a torque whether the field is uniform or non uniform in all orientations

Can be in equilibrium in one orientation

Can be in equilibrium in two orientations, both the euilibrium states are unstable

$θ = 0^{\circ}$ stable equilibrium
$θ = 18 0^{\circ}$ unstable equilibrium

θ=0∘ stable equilibrium θ=180∘ unstable equilibrium

$θ = 0^{\circ}$ stable equilibrium
$θ = 18 0^{\circ}$ unstable equilibrium
