Magnetic Ceramics

Magnetic Ceramics Marzia Hoque Tania Introduction ? magnetized force is the force of standoff or repugnance of a magnetised material receivable to the arrangement of its atoms, oddly its electrons. ? All magnetized phenomena result from forces between electric charges in motion. Demonstration of the magnetised flake associated with (a) an orbiting electron and (b) a crook around electron. Classifications ? There are conglomerate types of charismatic material classified ad by their magnetised susceptibilities: diamagnetic paramagnetic and ferromagnetic/ferrimagnetic.  reeking Magnetism Diamagnetism ? ? ? ? ? generate magnetic dipoles directed reverse to the external magnetic vault of heaven of a function. Requirements: atoms with completely filled orbitals Magnetic bit: no magnetic moment without applied field compensation of spin moments permeability / susceptibility: ?r< 1 , ?m < 0 (weak effect) Materials: idle gases, loft wat ch crystals, semiconductors, Cu, Au, Ag  wonky Magnetism: Diamagnetism ? disquietude of magnetic moments (H = 0): ? preserveion on lines of flux in a homogeneous magnetic field:  rickety Magnetism: Diamagnetism  imperfect Magnetism: Diamagnetism Weak Magnetism: Diamagnetism Weak Magnetism Paramagnetism ? coalition of imperishable magnetic dipoles in the direction of the external magnetic field.

? requirements: atoms with partiall(a)y filled orbitals ? magnetic moment: permanent magnetic moment 0 (weak effect) ? materials: Alkali- and transition metals, out of date realm metals O2, Al, Sn, Pt Weak Magnetism: Paramagne! tism ? direction of magnetic moments (H = 0): ? impact on lines of flux in a homogeneous magnetic field: Weak Magnetism: Paramagnetism Weak Magnetism: Paramagnetism Weak Magnetism: Paramagnetism Strong Magnetism Ferromagnetism ?
