If a copper rod (free to move and rotate) is brought in a region of a non-uniform magnetic field, then it will align itself

Options

A. along the direction of the magnetic field, at a location where the magnetic field is strongest.
B. along the direction of the magnetic field, at a location where the magnetic field is weakest
C. perpendicular to the directioni of the magnetic field, at a location where the magnetic field is strongest
D. perpendicular to the direction of the magnetic field, at a location where the magnetic field is weakest.

Answer

D

Explanation

Copper is diamagnetic so the copper rod will align itself perpendicular to the direction of the magnetic field, at a location where the magnetic field is weakest
