Electromagnetism & Magnetism Applications

Electromagnetism & Magnetism Applications Magnetism and moving electrons are closely related to each other. The three phenomena pertaining to electromagnetism are: Moving electric charges produce magnetic fields. Magnetic fields exert forces on moving electric charges. Changing magnetic fields in the presence of electric charges cause electrons to flow In 1820, Danish physicist Hans Oersted noted [...]

Electromagnets Solenoids

Electromagnets & Solenoids Electromagnets are a non-permanent magnets that produced magnetic field. The magnetic field is created by a flow of an electric current through the coil. The magnetic field disappears when the current ceases (or in the case electromagnets of a permanent electromagnet, the magnetic field is present until a current is applied). As [...]
