Science: Relationship between Electricity and Magnetism

Relationship between Electricity and Magnetism

1. When a current passes through a coil of wire, it generates a magnetic field along its axis. This was discovered by Hans Christian Dersted

2. If a loop of wire is moved through a magnetic field, a current is induced in the wire (ex. transformer, generator). Discovered by Michael Faraday

The magnet, in the ancient times, was called lodestone.
