A diamagnetic substance placed in a non-uniform magnetic field
Answer: (C) moves from the stronger to the weaker region
Concept. A diamagnetic material acquires a weak magnetisation opposite to the applied field, so its energy is lower where the field is weaker.
Step 1. Direction of the force. The force pushes the sample from the stronger towards the weaker field region. (Paramagnets and ferromagnets are pulled the other way.)
Answer. It moves from the stronger to the weaker region (Option C).
