PPT-Magnetism ● An electric charge experiences a magnetic force when moving in magnetic

A moving charge produces magnetic field There are two basic ideas in our introductory study of magnetism FIRST THINGS FIRST THEIR MAJESTY THEMSELVES MAGNETS The ancient Greeks originally those near the city of Magnesia and also the early Chinese knew about strange and rare stones possibly chunks of iron ore struck by lightning with the power to attract iron A steel needle stroked with such a lodestone became magnetic as well .

Torque on a current loop in a magnetic field, magnetic dipole moment. Physics 2415 Lecture 16. Michael Fowler, . UVa. Today’s Topics. Electric motors and galvanometers. Ratio of charge to mass for an electron. Hall Effect. Mass spectometry. Reviewing Essential Facts:. 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. . HW2:Chapter 21, Pb.1, Pb.12, Pb.13, Pb.25, .

The symbol . k. is a proportionality constant known as the Coulomb's law constant. The value of this constant is dependent upon the medium that the charged objects are immersed in. In the case of air, the value is approximately 9.0 x 10^9 N • m^2 / C^2. . Section 1: Magnetism. Section 2: Electricity and Magnetism. Section 3: Producing Electric Current. Section 1: Magnetism.
