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. It can be used to determine the direction of current in a generator's windings. 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. The current in the wire can have two possible directions. Fleming's right-hand rule gives which direction the current flows.

  • 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. It can be used to determine the direction of current in a generator's windings. 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. The current in the wire can have two possible directions. Fleming's right-hand rule gives which direction the current flows. The right hand is held with the thumb, index finger and middle finger mutually perpendicular to each other (at right angles), as shown in the diagram. * The thumb is pointed in the direction of the motion of the conductor relative to the magnetic field. * The first finger is pointed in the direction of the magnetic field. By convention, it's the direction from North to South magnetic pole. * Then the second finger represents the direction of the induced or generated current within the conductor (from + to −, the terminal with lower electric potential to the terminal with higher electric potential, as in a voltage source) The bolded letters in the directions above give a mnemonic way to remember the order. Another mnemonic for remembering the rule is the initialism "FBI", standing for Force (or otherwise motion), B the symbol for the magnetic field, and I the symbol for current. The subsequent letters correspond to subsequent fingers, counting from the top: thumb → F; first finger → B; second finger → I. 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. (en)
  • フレミングの右手の法則(フレミングのみぎてのほうそく、英: Fleming's right hand rule)は、ジョン・フレミングによって考案されたもので、磁場中で導体が運動するときにその導体内に電磁誘導により起電力が発生する現象において、磁場の向きと導体の運動方向と起電力の向きの関係を右手の指で示す方法である。フレミング右手の法則とも呼ばれる。 (ja)
  • La regola della mano destra di Fleming (per i generatori) mostra la direzione del flusso di corrente indotta quando un conduttore si muove in un campo magnetico. La mano destra deve essere tenuta col pollice, il dito indice e il dito medio reciprocamente angolati a 90 gradi, come mostra la figura seguente. A.Il pollice rappresenta la direzione del moto del conduttore.B.Il dito indice rappresenta il campo.C.Il dito medio rappresenta la corrente (nella direzione classica, da positivo a negativo). Esiste anche una Regola di Fleming per la mano sinistra (per i motori). Questa regola è stata chiamata così in onore dell'ingegnere britannico John Ambrose Fleming, che l'ha inventata. Un altro metodo per ricavare la fa forza elettromotrice indotta associando a ogni dito una iniziale: Pollice =propagazione[v] Indice = Induzione [B] Medio =movimento cariche [i] La forza che agisce sul filo conduttore si esprime come F= B*L*i, dove B è il campo magnetico, L è la lunghezza del filo e i è l'intensità di corrente.
