Such a field is created when an electric current flows. The stronger the current, the stronger the magnetic field formed around it. The magnetic field is measured in units of amperes per meter (A/m) or in milligaus (mG), or micro Tesla( µT) .קרא עוד >

A combination of several alternating currents (*) operating in parallel at different time periods (phases) depending on the definite time offsets of the electric power source (AC power). Multi-phase systems are useful in industry and for high efficient long distance transportation of electricity via high-voltage lines. Multi-phase system can be of 2,3 or more phases.
(*) See definition - AC
