Magnetic fields are produced by magnetism, the flow of electric charge, or fluctuating electric fields. In the first case, the magnetic field can be described as a region around a magnetic object, such as a magnet: Inside the magnet, the magnetic field...

Magnetism is a property of matter and it occurs in different forms and degrees in various conductors and insulators. For example, at low temperatures, metallic systems exhibit either superconducting or magnetic order. The degree of magnetism of a...

Electric and Magnetic Fields Referred to as EMF, the fields of energy surrounding electric power wires and other current-carrying devices. Electric power lines, household wiring, and appliances all carry electric current. Since the late 1970s, concerns...

Earth acts as though it were a huge dipole magnet with the positive and negative poles near the North and South Poles. This does not mean that Earth is literally a dipole magnet—there are too many variations in the field—but that the best...

In physics, the magnetic field is a field that permeates space and which exerts a magnetic force on moving electric charges and magnetic dipoles. Magnetic fields surround electric currents, magnetic dipoles, and changing electric fields. When placed in...
