In mathematics and physics, the right-hand rule is a convention and a mnemonic, utilized to define the orientation of axes in three-dimensional space and to determine the direction of the cross product of two vectors, as well as to establish the direction of the force on a current-carrying conductor in a magnetic field.
A Left Hand Rule for Faraday's Law. The sign of ΔΦ B, the change in flux, is found based on the relationship between the magnetic field B, the area of the loop A, and the normal n to that area, as represented by the fingers of the left hand. If ΔΦ B is positive, the direction of the emf is the same as that of the curved fingers (yellow ...
Change color of current arrow on the hand to match the blue color as the arrows for the coil current direction: 01:26, 31 December 2019: 540 × 470 (97 KB) TreeOfKnowledge: Direction of magnetic field (''B'') for an electrical coil.
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.

Left-hand people have to grab drinks with their right hand. Felix Kästle/picture alliance via Getty Images Grabbing a piping hot coffee with your non-dominant hand can be a recipe for spillage.
English: Right hand rule for a current-carrying wire in a magnetic field B. The thumb points in the direction of I (a positive current; the "+" and "−" indicate relative voltages for a resistive wire). The fingers point in the direction of B. The Lorentz force then points upwards perpendicular to the palm
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]
