Magnetic Field

A magnetic field can be generated in two ways: either around a magnet or in the vicinity of a moving electric field (when electric charge carriers such as electrons move through space or within an electrical conductor). Magnetic and electric fields interact differently depending on the environment into which they are placed.

An object placed in a magnetic field experiences a force which depends on its orientation within the field. Properties of a magnetic field are rendered in electromagnetism, which is the basis of technological advancements such as bullet trains, elevators, escalators and cathode-ray tube televisions.
