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

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 and negative charge

The conservation of charge is a fundamental principle of physics stating that the total electric charge in an isolated system remains constant over time. This principle implies that charge can neither be created nor destroyed, only transferred from one form to another.

Conservation Of Charge

An isolated system is a physical system that does not interact with its surroundings, meaning it does not exchange energy or matter with the environment. This idealized concept is useful in thermodynamics and physics for understanding conservation laws, as it helps simplify the analysis of energy transformations within the system.

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.
