Question

If a diamagnetic substance is brought near north or south pole of a bar magnet, it is

Answer 1

Diamagets

1. Diamagnetic materials are substances that are usually repelled by a magnetic field
2. They have no free electrons in their orbitals.
3. When an external magnetic field is applied, dipoles are induced in the diamagnetic materials in such a way that induced dipoles opposes the external magnetic field according to Lenz’s law.

Thus, when a diamagnetic substance is brought near the north or south pole of a bar magnet, it is repelled.
