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 [...]

How does Magnetism Affect a Watch?

How does Magnetism Affect a Watch? Watches can be adversely affected by magnetism and may gain or lose time. It is important not to leave a watch close to magnetic objects for a long periods. In particular, cell phones, television and PC speakers, magnetic necklaces, handbag clasps, hair-driers, electric razors, magnetic parts of refrigerators are [...]

Programmable Magnets

Programmed magnets, Programmable Magnets, polymagnets, Correlated magnet pairs, Programmable Magnetized Magnet Programmable Magnets, Programmed magnets, or polymagnets are magnetic structures that incorporate correlated patterns of magnets with alternating polarity, designed to achieve a desired behavior and deliver stronger local force. By varying the magnetic fields and strengths, different mechanical behaviors can be controlled. Correlated magnet [...]
