For a description of the force exerted on particles due to electromagnetic interaction of electromagnetic radiation with matter pdf, see Lorentz force. Electromagnetic may also refer to the use of an electromagnet. This article includes a list of references, but its sources remain unclear because it has insufficient inline citations.
Please help to improve this article by introducing more precise citations. Electromagnetism is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles.
The other three fundamental interactions are the strong interaction, the weak interaction and gravitation. Lightning is an electrostatic discharge that travels between two charged regions. The word electromagnetism is a compound form of two Greek terms, ἤλεκτρον ēlektron, “amber”, and μαγνῆτις λίθος magnētis lithos, which means “Μagnesian stone”, a type of iron ore. Electromagnetic phenomena are defined in terms of the electromagnetic force, sometimes called the Lorentz force, which includes both electricity and magnetism as different manifestations of the same phenomenon.
