In physics, electromagnetism is an interaction that occurs between particles with electric charge via electromagnetic fields. The electromagnetic force is one of the four fundamental forces of nature.
Electromagnetic interactions are responsible for the glowing filaments in this plasma globe.
Foam peanuts clinging to a cat's fur due to static electricity. The cat's fur becomes charged due to the triboelectric effect. The electric field of the charged fur causes polarization of the molecules of the foam due to electrostatic induction, resulting in a slight attraction of the light plastic pieces to the fur. This effect is also the cause of static cling in clothes.

…dominant force in the interactions of atoms and molecules. Electromagnetism describes and relates the three distinct but closely intertwined phenomena of electricity, magnetism, and optics. In the study of electromagnetism these phenomena are described by the 3 sub-disciplines: electrostatics, magnetostatics, and…
Electricity is invisible, but it can yield visually observable phenomena, shown here with the flash of lightning and various forms of electric light in the buildings.
A fictional portrait of Thales, the earliest known researcher into electricity
Benjamin Franklin conducted extensive research on electricity in the 18th century, as documented by Joseph Priestley (1767) History and Present Status of Electricity, with whom Franklin carried on extended correspondence.
Michael Faraday's discoveries formed the foundation of electric motor technology.
