$A$ perfectly diamagnetic sphere has a small spherical cavity at its centre, which is filled with a paramagnetic substance. The whole system is placed in a uniform magnetic field $\overrightarrow{B}$. Then the field inside the paramagnetic substance is:
- A$Zero$
- B$\overrightarrow{B}$
- Cmuch larger than $|\overrightarrow{B}|$ but opposite to $\overrightarrow{B}$
- Dmuch larger than $|\overrightarrow{B}|$ and parallel to $\overrightarrow{B}$
