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 [...]

Magnetism as an Energy Source

Magnetism as an Energy Source: Understanding Magnetic Force This article will discuss magnetic fields and electromagnetism. An invisible force occurs between two magnets when they are brought close to each other. This force may be an attraction force that pulls the magnets together or a repulsion force that pushes them apart. See Figure 1. Magnetic [...]
