1.Define magnetic flux, flux density, magnetic field strength. State their units.

Answer»

Magnetic Flux:Magnetic flux is a measurement of the total magnetic field which passes through a given area. It is a useful tool for helping describe the effects of the magnetic force on something occupying a given area. The SI unit of magnetic flux is the weber (Wb) (in derived units: volt seconds), and the CGS unit is the maxwell

Flux Density: The flux density is the number of magnetic lines of flux that pass through a certain point on a surface. The SI unit is T (tesla), which is weber per square metre (Wb/m2) and the unit in the CGS system is G (gauss)

Magnetic Field Strength:Magnetic field strength is one of two ways that the intensity of a magnetic field can be expressed. Technically, a distinction is made between magnetic field strength H, measured in amperes per meter (A/m), and magnetic flux density B, measured in Newton-meters per ampere (Nm/A), also called teslas (T).
