Question

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

• A. In the region where magnetic field is strongest
• B. In the region where magnetic field is weakest and parallel to direction of magnetic field there
• C. In the direction in which it was originally suspended
• D. In the region where magnetic field is weakest and perpendicular to the direction of magnetic field there

Answer 1

Answer: (D)

Copper is a diamagnetic material, therefore its rod align itself where magnetic field is weaker and perpendicular to the direction of magnetic field there.
Hence, when a copper rod is suspended in a non-homogenous magnetic field region, then the rod when in equilibrium will align itself in the region where magnetic field is weakest and perpendicular to the direction of magnetic field there
