The best way to introduce the different types of magnetism is to describe how materials respond to magnetic fields. This may be surprising to some, but all matter is magnetic. It's just that some materials.

Every substance is formed from an assembly of atoms which can be either non-magnetic or magnetic. The magnetic materials are classified into five groups depending on their response to the magnetic field. Diamagnetic Materials; Paramagnetic Materials; Ferromagnetic Materials; Antiferromagnetic Materials; Ferrimagnetic.

So, when electrons are paired together, their opposite spins cause their magnetic fields to cancel each other. Therefore, no net magnetic field exists. Alternately, materials with some unpaired electrons will have a net magnetic field and will react more to an external field. Most materials can be classified as diamagnetic,.

face-centred cubic) structure containing two types of temperature, called the Curie temperature. Below magnetic sites which have antiparallel magnetic the Curie temperature a ferromagnetic material can moments of different magnitudes. Therefore the carry a strong remanent magnetisation, but above the elementary.

Magnetic domain

Ferromagnetic materials exhibit parallel alignment of moments resulting in large net magnetization even in the absence of a magnetic field. The elements Fe, Ni, and Co and many of their alloys are typical ferromagnetic materials. Two distinct characteristics of ferromagnetic materials are their (1) spontaneous magnetization.

Magnetism - Magnetic properties of matter | Britannica

In 1845 Faraday became the first to classify substances as either diamagnetic or paramagnetic. He based this classification on his observation of the force exerted on substances in an inhomogeneous magnetic field. At moderate field strengths, the magnetization M of a substance is linearly proportional to the strength of the.
