Fleming's rules are a pair of visual mnemonics for determining the relative directions of magnetic field, electric current, and velocity of a conductor.

There are two rules, one is Fleming's left-hand rule for motors which applies to situations where an electric current induces motion in the conductor in the presence of magnetic fields (Lorentz force). For example, in electric motors.[1] The purpose of the rule is to find the direction of motion in an electric motor.[2]

The second is Fleming's right-hand rule for generators, which applies to situations where a conductor moving through a magnetic field has an electromotive force induced in it as a result (Faraday's law of induction). The purpose of the rule is to find the direction of induced current when a conductor moves in a magnetic field.[3]
