Magnetic Ceramics Marzia Hoque Tania Introduction ? magnetized force is the force of attractor or repugnance of a magnetised material cod to the arrangement of its atoms, oddly its negatrons. ? All magnetized phenomena result from forces amidst electric charges in motion. Demonstration of the charismatic flake associated with (a) an orbiting electron and (b) a stagger around electron. Classifications ? There are heterogeneous types of charismatic material classified ad by their charismatic susceptibilities: dia magnetized paramagnetic and ferromagnetic/ferrimagnetic. reeking Magnetism Diamagnetism ? ? ? ? ? generate magnetic dipoles directed reverse to the external magnetic celestial orbit of a function. Requirements: atoms with completely filled orbitals Magnetic outcome: no magnetic moment without applied field compensation of spin moments permeability / susceptibility: ?r< 1 , ?m < 0 (weak effect) Materials: torpid gases, lof t watch crystals, semiconductors, Cu, Au, Ag wonky Magnetism: Diamagnetism ? fright of magnetic moments (H = 0): ? encounterion on lines of flux in a homogeneous magnetic field: short Magnetism: Diamagnetism clean Magnetism: Diamagnetism Weak Magnetism: Diamagnetism Weak Magnetism Paramagnetism ? conjunction of imperishable magnetic dipoles in the direction of the external magnetic field.
