Question

The magnetic susceptibility of a diamagnetic substance is:

• A. negative
• B. zero
• C. positive and low value
• D. positive and high value

Answer 1

Answer: (A)

negative

In a diamagnetic material, all electrons are paired. when an external magnetic field is applied, then an in divide magnetic field is created in the opposite direction.

Since the material repelled by the magnetic field and the material does not retain is the magnetic property after the remover of external magnetic field, they have a negative susceptibility.
