|Since paramagnetic materials are repelled from magnetic fields.|

|Two north poles repel each others. Two south poles repel each others. North pole south pole attracts each others.|

|Absolute permittivity is the measure of the resistance that is encountered when forming an electric field in a medium. In other words, permittivity is a measure of how an electric field affects, and is affected by, a dielectric medium. The permittivity of a medium describes how much electric field (more correctly, flux) is 'generated' per unit charge in that medium.|

|What is permanent magnetic material?|

|@Ardhi Rajarshi is wrong.
Para magnetism is a form of magnetism whereby certain materials are attracted by an externally applied magnetic field, and form internal, induced magnetic fields in the direction of the applied magnetic field.

|Yes, it's true. In paramagnetism, dipoles do not interaction with one another due to the thermal agitation.
Causing zero net magnetic moment.

|Para magnet: it has partially attracting property.
Dia magnet: it is repelled the magnet.
Ferro: strong attract property.
