Such substances, which are magnetized weakly when positioned in the same direction as the applied field in an external magnetic field are called paramagnetic substances.
They prefer to switch from the weaker part of the field to the stronger.
The magnetism which these substances exhibit is called paramagnetism.
Owing to incomplete cancellation of the electron spin and orbital magnetic moment, paramagnetic materials exhibit a permanent magnetic dipole moment.
Aluminum, platinum, manganese, chromium, sodium, calcium, lithium and tungsten are examples of paramagnetic material.
