Answer:
Paramagnetic materials have some unpaired electrons due to these unpaired electrons the net magnetic moment of all electrons in an atom is not added up to zero.
- Atomic dipole exists in this case.
- On applying external magnetic field the atomic dipole aligns in the direction of the applied external magnetic field.
- In this way, paramagnetic materials are feebly magnetized in the direction of the magnetizing field.
- These materials usually experience a weak attraction to magnets.
- Paramagnetism occurs mainly due to the presence of unpaired electrons in the material or due to the partial alignment of randomly oriented atomic dipole along the field.

- Tungsten
- Caesium
- Aluminium
