Curie's Law

Curie's Law

According to Curie’s Law, the magnetization in a paramagnetic material is directly proportional to the applied magnetic field. If the object is heated, the magnetization is viewed to be inversely proportional to the temperature. The law was discovered by the french physicist, Pierre Curie.

It can be framed into an equation.

M = C x (B/T)

Wherein,

M = Magnetism

B = Magnetic field(in Teslas)

T = absolute temperature (in Kelvins)

C = Curie constant

Curie’s law holds good for high temperature and not so strong magnetic fields.

What is meant by paramagnetic?

Paramagnetism relates to materials such as platinum or aluminium that are magnetized in a magnetic field and their magnetism extincts when the field doesn’t exist. Ferromagnetism are the materials like nickel and iron that retain their magnetic properties when the field is erased.

What is the Curie temperature?

The Curie temperature is the one at which ferromagnetic material turn to paramagnetic o heating. This kind of transition is used in optical storage media for erasing and inserting new data.
