Introduction to magnetic properties of solid and its types and its causes

Solids can be partitioned into various classes relying upon their reaction to attractive fields. 

(a) Paramagnetic (Weakly attractive): Such materials contain lasting attractive dipoles because of the nearness of particles, particles or atoms with unpaired electrons e.g. what's more, They are pulled in by the attractive field. They, be that as it may, lose their attraction without an attractive field. 

(b) Diamagnetic: They are feebly repulsed by attractive fields. Diamagnetism emerges because of the nonattendance of unpaired electrons e.g. (18 electron sort). 

(c) Ferromagnetic: It is caused by unconstrained arrangement of attractive minutes a similar way. 

(d) Ferrimagnetism: It happens when the minutes are adjusted in parallel and antiparallel headings in unequal number bringing about a net minute.
