There is also a Fleming's left-hand rule (for electric motors). The appropriately handed rule can be recalled from the letter "g", which is in "right" and "generator". These mnemonics are named after British engineer John Ambrose Fleming, who invented them. An equivalent version of Fleming's right-hand rule is the left-hand palm rule. [2]
The various FBI mnemonics (for electric motors) show the direction of the force on a conductor carrying a current in a magnetic field as predicted by Fleming's left hand rule for motors [1] and Faraday's law of induction. Other mnemonics exist that use a right hand rule for predicting resulting motion from a preexisting current and field.
Faraday's law of induction (or simply Faraday's law) is a law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force (emf). This phenomenon, known as electromagnetic induction , is the fundamental operating principle of transformers , inductors , and many types of electric ...
The purpose of the rule is to find the direction of motion in an electric motor. 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 ...
Ampère's right-hand grip rule, [6] also called the right-hand screw rule, coffee-mug rule or the corkscrew-rule; is used either when a vector (such as the Euler vector) must be defined to represent the rotation of a body, a magnetic field, or a fluid, or vice versa, when it is necessary to define a rotation vector to

From the right hand rule the field lines pass through the wire in an upward direction. From Faraday's law of induction , when the time-varying magnetic field is increasing, it creates a circular current (E, red loops) within the wire around the magnetic field lines in a clockwise direction.
