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.
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]
Sir John Ambrose Fleming (29 November 1849 – 18 April 1945) was an English electrical engineer and physicist who invented the vacuum tube, [2] designed the radio transmitter with which the first transatlantic radio transmission was made, and also established the right-hand rule used in physics.

Indonesian meals are commonly eaten with the combination of a spoon in the right hand and fork in the left hand to push the food onto the spoon. Knife however, is absent from dining table, thus most of the ingredients such as vegetables and meat are already cut into bite-size pieces prior to cooking.

If the right-hand grip rule and the right-hand rule were both changed to left-handed (this is equivalent to changing to a left-handed coordinate system, or a parity flip in which the right- and left- sides of the Universe are exchanged) all these equations would still work, they would give the correct direction for forces and currents, but the ...
