# A copper rod is suspended in a non-homogeneous magnetic field region. How will it align itself in equilibrium? a) in the region where the magnetic field is strongest b) in the region where the magnetic field is weakest and parallel to the direction of magnetic field there c) in the direction in which it was originally suspended d) in the region where the magnetic field is weakest and perpendicular to the direction of the magnetic field

Diamagnetic materials are repelled by a magnetic field. Applied magnetic field creates an induced magnetic field in the material which is in the opposite direction. This causes a repulsive force between the two.
Copper being a diamagnetic, the rod in equilibrium will align so that above mentioned force of repulsion is minimum.
