List of Magnetic Materials Every electron in an atom behaves like a small magnet. Looks like you’ve clipped this slide to already. Ferrimagnetism. They are slightly magnetized when placed in a very string magnetic field and act in the direction opposite to that of applied magnetic field. You can change your ad preferences anytime. Antiferromagnetism. All the magnetic materials are metals. The examples of paramagnetic materials are aluminum, chromium, oxygen, manganese, alkali, alkaline earth metal etc. What is Superconductor : Types, Materials & Properties There are two types of materials like metals as well as insulators. MAGNETIC MATERIALS Origin of Magnetism Types of Magnetism Hard and Soft Magnets Magnetic Materials Fundamentals and Device Applications Nicola Spaldin – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 415658-OTg0N • Ferromagnetic • Paramagnetic • Diamagnetic • Magnetically Soft material • Magnetically Hard material 6. Introduction Finally, other types of important magnetic materials are briefly discussed. Induction type high magnetic force separator KID-R For removal of weak magnetic bulk materials. I… No public clipboards found for this slide. • A type of material that is highly attracted to magnets and can become permanently magnetized is called as ferromagnetic. For example the relative permeability of bismuth is 0.00083, copper is 0.000005 and wood is 0.9999995. Prepared By :- Diamagnetic 2.
