A copper rod is suspended in a nonhomogeneous magnetic field region. The rod when in equilibrium will align itself

Options

  1. Ain the region where magnetic field is strongest
  2. Bin the region where magnetic field is weakest and parallel to direction of magnetic field there
  3. Cin the direction in which it was originally suspended
  4. Din the region where magnetic field is weakest and perpendicular to the direction of magnetic field there.

Correct answer

D. in the region where magnetic field is weakest and perpendicular to the direction of magnetic field there.

Step-by-step 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.
