In 1820, Danish physicist Hans Christian Oersted discovered that an electric current flowing through a wire could deflect a compass needle. This finding led other scientists to believe that there might be a connection between electricity and magnetism. In 1831, English scientist Michael Faraday conducted experiments that showed that a moving magnetic field could induce… Read More

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

Electromagnetism is one of the four fundamental forces of nature and the other three are gravity, weak interaction, and strong interaction. It is the force that governs the behavior of electrons and protons, and it is responsible for most of the physical phenomena we see in everyday life. Electromagnetism arises from two basic principles: electricity… Read More
