In which orientation,a dipole placed in a uniform electric field is in unstable equilibrium?

If there is uniform magnetic field of in the positive z direction , in which orientations the loop would be in (i) stable equilibrium and (ii) unstable equilibrium ?

A rectangular loop of sides 10 cm and 5 cm carrying a current I of 12 A is placed in different orientations as shown in the figures below , If there is a uniform magnetic field of 0.3 T in the positive z direction, in which orientations the loop would be in (i) stable equilibrium and (ii) unstable equilibrium ?

A short bar magnet of magnetic moment m= 0.32JT^-1 is placed in a uniform extemal magnetic field of 0.15T. If the bar is free to rotate in the plane of the field, which orientations would correspond to its (i) stable and (ii) unstable equilibrium? What is the potential energy of the magnet in each case?

A rectangular loop of sides 10 cm and 5 cm carrying a current 1 of 12 A is placed in different orientations as shown in the figure below: If there is auniform magnetic field of 0.3 t in the positive z direction , in which orientations the loop would be in (i) stable equilibrium and (ii) unstable equilibrium ?
