PPT-PHY 042: Electricity and Magnetism

Electrostatics Prof Hugo Beauchemin 1 The Maxwell equations 2 A set of 4 differential equations completely determining How charges produce electric E or magnetic B fields How the variation of an E or a B field generates a B or an E. 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. . Electrodynamics. Prof. Hugo . Beauchemin. 1. Introduction. The strategy adopted to reveal the structure of E&M was to:. Start from . a concrete . experimental setup to infer uniformities . about. 10-10:50 AM MWF Olin 107. Plan for Lecture 30:.

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. Maxwell’s equations. Prof. Hugo Beauchemin. 1. Limitation of Ampere’s law. With Faraday’s law, we extended the electrostatics E-field to non-steady current, providing a set of equations for E-fields valid in any classical situations and describing all possible experiments. 1.
