A copper rod is suspended in a nonhomogeneous magnetic field region. The rod when in equilibrium will align itself
  1. in the region where magnetic field is strongest
  2. in the region where magnetic field is weakest and parallel to direction of magnetic field there
  3. in the direction in which it was originally suspended
  4. in the region where magnetic field is weakest and perpendicular to the direction of magnetic field there.

Solution

Copper is a diamagnetic material, therefore its rod align itself where magnetic field is weaker and perpendicular to the direction of magnetic field in that region.
