Curie's Law - Statement and Formula

We have discussed various important laws of Physics in previous sessions. In this article, let us learn in detail the curie’s law, curie’s law formula, paramagnetism and curie temperature.

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.
Curie’s Law Formula
Curie’s Law can be framed into an equation.
M = C x (B/T)
Wherein,
M = Magnetism
B = Magnetic field(in Tesla)
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 becomes extinct when the field doesn’t exist. Ferromagnetism is 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 turns to paramagnetic on heating. This kind of transition is used in optical storage media for erasing and inserting new data.
