Electrical charge is a fundamental property of matter that causes it to experience a force when placed in an electromagnetic field. It comes in two types, positive and negative, and is conserved in isolated systems, playing a crucial role in electromagnetic interactions.

fundamental property of matter

An electromagnetic field is a physical field produced by electrically charged objects, which affects the behavior of charged objects in its vicinity. It is fundamental to the operation of many technologies and underlies the principles of electromagnetism, one of the four fundamental forces of nature.

Positive Charge

Negative charge refers to the electric charge carried by electrons, which results from an excess of electrons relative to protons. This charge influences how particles interact, leading to phenomena such as attraction to positively charged particles and repulsion from other negatively charged particles.

Negative Charge

conserved in isolated systems

Electromagnetic interactions are fundamental forces that occur between charged particles, mediated by the exchange of virtual photons. These interactions govern a wide range of phenomena including the behavior of atoms, the propagation of light, and the forces in electrical and magnetic fields.
