Electric and Magnetic Fields
... The earth’s magnetic field is the force that causes a compass to always point north. Magnetic fields also result from current or the flow of electricity in a wire; field strength increases as the current increases and decreases as distance from the wire increases. Objects such as trees, shrubs and b ...
