Q. 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

NTA AbhyasNTA Abhyas 2020

Solution:

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
