Magnetism is one of the most important forces in the universe. It is responsible for the Sun’s heat and light, and it drives the Earth’s climate. Magnetism also creates beautiful auroras, and it can be harnessed to generate electricity. All matter is made up of atoms, which are tiny particles that are constantly moving. Atoms… Read More

The word “electron” was coined in 1894 by Irish physicist George Johnstone Stoney (1826–1911). He suggested that electrons were components of atoms and proposed the name “corpuscle” for them. In 1897, English physicist J. J. Thomson (1856–1940) discovered electrons in cathode ray experiments and proposed that they were parts of atoms as well. Electrons are… Read More

Electricity is the set of physical phenomena associated with the presence and motion of electric charge. Although initially considered a phenomenon separate from magnetism, since the development of Maxwell’s equations, both are recognized as part of a single phenomenon: electromagnetism. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges,… Read More
