In electromagnetism, Fleming's right-hand rule (for generators) shows the direction of induced current when a conductor attached to a circuit moves in a magnetic field.
When a conductor such as a wire attached to a circuit moves through a magnetic field, an electric current is induced in the wire due to Faraday's law of induction.
Fleming's right-hand rule gives which direction the current flows.

These mnemonics are named after British engineer John Ambrose Fleming, who invented them.
