Electricity can also produce magnetism

Electrical current flowing through a wire produces a magnetic field. If the wire is wound into a coil, it will produce a stronger magnetic field, similar to that of a bar magnet: each end of the coil will become a magnetic pole. This effect was discovered by Danish physicist Hans Christian Oersted (1777–1851). He noticed that electric current disturbed the normal functioning of magnetic compasses.

ElectromagnetismA form of magnetic energy produced by the flow of an electric current through a metal core. Also, the study of electric and magnetic fields and their interaction with charges and currents. is a form of magnetic energy produced by the flow of an electric current through a metal core. It has many applications in our modern technology. Stereo speakers are one of the most common applications....
