MAGNETIC CLASSIFICATION OF MATERIALS BASIC INFORMATION AND TUTORIALS

Magnetic Classification of Materials
What Are the Magnetic classifications of Materials?


Material Type Description

Nonmagnetic No magnetic reaction.

Diamagnetic Induced dipole moment opposes applied field.
Repelled by bar magnet.
Very weakly magnetic.

Paramagnetic Induced dipole moment aligns to applied field.
Attracted by bar magnet.
Weakly magnetic.

Ferromagnetic Induced dipole moment aligns to applied field.
Attracted by bar magnet.
Very strongly magnetic.
Has memory and so can be used to create permanent magnets.
High electrical conductivity.

Ferrimagnetic Type of ferromagnetic material.
Induced dipole moment aligns to applied field.
Attracted by bar magnet.
Very strongly magnetic.

Ferrites Type of ferrimagnetic material.
Induced dipole moment aligns to applied field.
Attracted by bar magnet.

Very strongly magnetic.
Low electrical conductivity.

Superparamagnetic Material mixture: ferromagnetic particles suspended in a plastic binder.
Induced dipole moment aligns to applied field.
Very strongly magnetic.
Has memory, which allows for uses in audio, video, and data recording.
