Magnetic Properties of Materials, Types of Substances, Fundamental of Or...


MAGNETIC PROPERTIES OF MATERIALS

We know that matter is made up of atom. Each atom consists of a positively charged nucleus around which electrons revolve in various discrete orbits. Each revolving electron is equivalent to a tiny current loop and gives a dipole moment to the atom. Besides this, electrons also spin on it own axis and this spin also produces a magnetic dipole moment. There are three types of Substances
i. Diamagnetism Substances
ii. Paramagnetism Substances
iii. Ferromagnetism Substances
