Electromagnetism
Electromagnetism
Electromagnetism (/ɪˌlɛktroʊˈmæɡnɪtɪzəm/) is a branch of Physics that deals with the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles. The word "electromagnetism" is derived from the Greek words "electron" meaning amber, and "magnetism" from Magnesia, a region in ancient Greece known for its magnetic ores.
The electromagnetic force is one of the four fundamental forces and exhibits electromagnetic fields such as Electric Fields, Magnetic Fields, and Light. Electromagnetism is the reason behind many physical phenomena such as the interaction of Electrons and Photons, and the interaction of Electric Currents and Magnetic Fields.
Related Terms
- Electric Charge: A fundamental property of matter that can be either positive or negative. Two objects with the same type of charge repel each other, while objects with opposite types of charge attract each other.
- Electric Field: A region around a charged particle or object within which a force would be exerted on other charged particles or objects.
- Magnetic Field: A field of force produced by moving electric charges, represented by lines of force.
- Photon: A particle representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has zero rest mass.
- Electron: A stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.
- Electric Current: A flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire.
