elektromágnesességet

Elektromágnesesség is the physical phenomenon by which electrically charged particles exert forces on each other. These forces are mediated by electromagnetic fields, which are generated by electric charges and electric currents. This fundamental force is one of the four basic forces of nature, alongside gravity, the strong nuclear force, and the weak nuclear force.

The interaction of electric and magnetic fields is described by Maxwell's equations, a set of four fundamental equations in classical electromagnetism. These equations unify electricity and magnetism, showing that they are two aspects of the same phenomenon. Light itself is understood as an electromagnetic wave, a propagating disturbance in these fields that travels at the speed of light.

Electromagnetism has a wide range of applications. It is the basis for electricity generation, electric motors, radio, television, radar, and all forms of wireless communication. It also plays a crucial role in chemistry, as chemical bonds are electromagnetic in nature. The study of electromagnetism, or electromagnetics, is a vast field encompassing phenomena from static electric charges to the propagation of electromagnetic waves across the universe.
