All substances show some kind of magnetic behavior. After all, they are made up of charged particles (electrons and protons). It is the way in which electron clouds arrange themselves in atoms and how groups of these atoms behave that determines the magnetic properties of the material.
The orientation of the spin of the electrons in an atom, the orientation of the atoms in a molecule or alloy, and the ability of domains of atoms or molecules to line up are the factors that determine how a material responds to a magnetic field.
Magnetic Classification of materials
Ferromagnetic
Paramagnetic
Diamagnetic
Nonmagnetic
Ferromagnetic
Also called simply magnetic are materials highly permeable and greatly susceptible to induction
This type of materials are strongly attracted by a magnetic force.
Examples:
Iron
Cobalt
Nickel
Paramagnetic
Paramagnetic materials have low permeability and weak attraction to magnetic fields.
They have only a slight majority of dipoles in the same direction.
Examples:
Platinum
Aluminum
Diamagnetic
They weakly repelled by all magnetic fields, including both north and south poles.
This property is so weak that it is easily obscured by other types of magnetic induction.
Examples:
Beryllium
Lead
Bismuth
Nonmagnetic
These materials are not attracted by a magnet and cannot be magnetized
This classification includes most materials.
Example:
Plastic
Rubber
Water
Conclusion
Magnets will strongly attract ferromagnetic materials, weakly attract paramagnetic materials, and weakly repel diamagnetic materials. Ferromagnetic materials have the most magnetic uses. The main practical use for diamagnetic materials is in magnetic levitation.
