Electromagnetism

 Electromagnetism

    Electromagnetism is an interaction between particles with electric charge via electromagnetic fields. It involves the electric and magnetic fields, where any charged particle experiences the effect of both electric fields, as well as magnetic fields. It is one of the four fundamental forces of nature, dominant in the interactions of atoms and molecules. Electromagnets are created and work by running an electrical current through coil with a metal core, which creates a magnetic field around the coil. Once the electricity current is removed, the magnetic field disappears. In manufacturing, electromagnets are used for lifting and handling heavy objects, magnetic separation, and electromagnetic forming and joining processes. In the medical field, they are used for imaging and treatments, such as cancer, in MRI machines with X-ray equipment.

    The strength of electromagnets is present in our day-by-day in motors, generators, and even for therapy. The discovery of electromagnets made a far-reaching change on technology and everyday life since it helped develop electric power generation and distribution, which transformed industries and enabled the use of electrical apparatuses in homes and businesses. Examples of these are telecommunications, including the telephone, radio, and the most precious thing for many people, the internet... which obviously transformed communication and information sharing.
