PPT-PHY 042: Electricity and Magnetism

Maxwells equations Prof Hugo Beauchemin 1 Limitation of Amperes law With Faradays law we extended the electrostatics Efield to nonsteady current providing a set of equations for Efields valid in any classical situations and describing all possible experiments. What do doorbells, microwaves, and speakers all have in common? They all use . Electricity. and . Magnetism. . You experience Electricity and Magnetism in many areas of life, even if you don’t see it. . p. erovskite. oxides. Phillip Barton. 05/28/10. MTRL 286G. Final Presentation. Comparison of 3d and 4d magnetism. 3d transition metals Fe, Co, and Ni are ferromagnetic, however no 4d or 5d are ferromagnetic (except reports of . What is magnetism?. Force of attraction or repulsion due to electron arrangement. Magnetic forces are the strongest at the poles. Magnets have two poles: North and South. Magnetic poles and fields. Magnets always have two poles. Multipole. expansion. Prof. Hugo Beauchemin. 1. Introduction . When we studied Gauss’ law, we saw that the field created by a sphere was the same as the one created by a point charge at the center of the sphere. Why?. 1.
