Diamagnetic Substances:$ The substances which are weekly magnetized when placed in an external magnetic field, in a direction opposite to the applied field are called diamagnetic substances.
Example:$ Copper, lead, gold, silver, zinc, antimony, bismuth, etc.
Properties:$
- These substances are repelled by a magnet
- Atomic orbitals of these substances are completely filled
- It develops weak magnetization in a direction opposite to the direction of the applied magnetic field
- As soon as the magnetizing field removed, it loses its magnetization
- When placed in a non-uniform magnetic field, it tends to move from stronger to weaker regions of the magnetic field
- When placed in a uniform magnetic field, it aligns itself perpendicular to the direction of the magnetic field
- Magnetic susceptibility is a small negative value
- Relative permeability is close to one and always less than 1
- Magnetic permeability is slightly less compared to free space
ans- 1- superconductors
