Electromagnetic - Assignment ExampleAll the objectives would be achieved by carrying out several(prenominal) activities such as tests for magnetic shielding, falling magnets and the design of the motor. The lab activity was also aimed at using PHET simulation softw be to carry out whatsoever electromagnetic tests.Magnetic shielding is the act of reducing the electromagnetic field contained in space by blocking the area with barriers made of either conductive or magnetic material. Magnetic shielding, however, does not prevent a magnetic field, preventing lines of flux from traveling from the North Pole to the South Pole of a magnet. However, the palm can be redirected. Any ferromagnetic metal can be used as a shielding metal. A ferromagnetic metal is a material containing either nickel-iron or cobalt. Most of the steel materials are ferromagnetic metals and work well as redirecting shield. Steel is, however, most used because it is less overpriced and widely available. The thicknes s of the shielding material matters to individual levels. When a shield is so thin, it becomes saturated with magnetic field lines and cannot hold any to a greater extent lines of flux. dull shielding is therefore required to carry a maximum number of flux lines. A thick shield does not necessarily mean adding more of steel material. Adding steel thickness does not improve the shielding much. In such cases where saturation is an issue, multiple layers of the shielding material are used. There are some specialized materials especially designed for magnetic shielding. The Specialized magnetic shielding materials are always designed to have a higher congeneric permeability and a lower saturation point. The right shielding materials depend on the particular shielding problem. For instance for a sensitive electronic, Metals can give an excellent shielding than steel. Or large applications involving large, powerful neodymium magnets,
