Key Concepts

Ferromagnetism

Ferromagnetism is a form of magnetism in which the magnetic moments of atoms in a material align parallel to each other, resulting in a strong, permanent magnetic property. This characteristic is naturally present in certain elements such as iron, nickel, and cobalt, defining many common magnetic materials.

Magnetism

Magnetism is the physical phenomenon by which materials exert an attractive or repulsive force on other materials. It arises due to the motion of electric charges and intrinsic magnetic moments of elementary particles, playing a fundamental role in both natural phenomena and technological applications.

Magnetic Materials

Magnetic materials are substances that respond to magnetic fields, either by being attracted or by generating their own magnetic fields. They are classified based on their magnetic properties into categories like ferromagnetic, paramagnetic, and diamagnetic, with ferromagnetic materials exhibiting the strongest and most persistent magnetic behavior.
