Bohr Magneton
Bohr Magneton is magnetic dipole moment associated with an atom due to orbital motion and spin of an electron. The Bohr magneton (symbol ) is a physical constant and the natural …
Ampere’s Law
Ampere’s Law is an integral part of the concept of electromagnetism and is also known as Ampère’s circuital law. Ampère’s law is an alternative expression of Biot Savart Law. History …
Biot Savart Law
Biot Savart Law is basically an equation describing the magnetic field generated by a constant electric current. It establishes a relationship between the magnetic field and the magnitude, direction, length, …
Curie’s Law
Curie Law is a law in magnetization that establishes a relation between the magnetic susceptibility and the magnetisation of a paramagnetic material. A paramagnetic material is a metal that is …
Curie Temperature
Curie Temperature (), also known as Curie Point, is the temperature at which certain magnetic materials undergo a sharp change in their magnetic properties. This point was named after Pierre …
