Show Hint
Diamagnetic materials always oppose the applied magnetic field:
\[
M=-H
\]
Examples: Bismuth, copper, silver, water.

The Correct Option is D
Solution and Explanation
Concept:
The magnetic field inside a material is:
\[
B=\mu_0(H+M)
\]
where:
• \(H\) = magnetic field intensity
• \(M\) = magnetization
Diamagnetic materials develop magnetization opposite to the applied field.
Step 1: Use the given condition. Given: \[ \mu_0(H+M)=0 \] Since \(\mu_0 \neq 0\), \[ H+M=0 \] Thus: \[ M=-H \]
Step 2: Interpret the physical meaning. Negative sign shows magnetization is opposite to the applied magnetic field. This is the characteristic property of diamagnetic substances. Hence the material is: \[ \boxed{\text{Diamagnetic}} \]
