Fleming's right-hand rule
A mnemonic used in electromagnetism to determine the direction of induced current when a conductor moves in a magnetic field. Often contrasted with 左手の法則 (Fleming's left-hand rule) for motor action.
See also: フレミングの法則
Using the right-hand rule, you can find the direction of the induced current.
Fleming's left-hand rule is used for motors (force on a current-carrying conductor), while 右手の法則 is used for generators (induced current).
Fleming's rules collectively; 右手の法則 is the right-hand version.
From 右手 (right hand) + の (possessive particle) + 法則 (rule, law). A calque of English 'right-hand rule', attributed to John Ambrose Fleming.
