magnetic properties of solid


Solid substance shows magnetic properties.
There are different type-
1. Paramagnetic: - a solid substance which is weakly attached from magnetic field that is called paramagnetic. This property of substance is called paramagnetic properties.
Magnetic value always greater than 0 of paramagnetic substance.
Ex- sulfur, Phosphorus and nitrogen, etc.

2. Diamagnetic: - sorry substance which is not attached from magnetic field that is called diamagnetic. This property of substance is called Diamagnetic properties.
Magnetic value always equal to zero of diamagnetic substances.
Ex- Helium, Neon, Argon, Krypton, etc.

3. Ferromagnetic: - a solid substance which is strongly attached from magnetic field that is called ferromagnetic. This property of substance is called ferromagnetic properties.
In Ferromagnetic substance, maximum number of unpaired electron present.

Ex- chromium iron Cobalt nickel etc.

4. Antiferromagnetic: - a solid substance in which electron regular arrange in same spin and opposite spin that is called antiferromagnetic. This property of substance is called antiferromagnetic property.
Ex- FeO , MnO2, MnO, etc.

*Ferromagnetism: - A solid substance in which electron irregular arrange in same and opposite spin that is called ferromagnetism.

*Dialectical properties:- those solid substance in which electric current does not flow that is called dielectric substance. This property of substance is called dielectric property.

Dielectric properties are of two types-

1 pyroelectric properties: - a solid substance in which electric current slightly flow after heating that is called pyro electrical properties.

2 Piezoelectric properties: - substance image electric current flow after giving mechanical force, that is called electrical properties.

#radius ratio: - the ratio of radius of cation and radius of anion is called radius ratio.
Radius ratio= radius of cation/radius of anion
