The right-hand rule fixes the orientation of a cross product and relates the circulation direction of an electric current to the direction of its magnetic field.
The right-hand rule is a mnemonic used in physics and mathematics to determine the direction of certain vector quantities in three-dimensional space. There are different applications of the right-hand rule depending on the context, but they generally involve using the fingers of the right hand to establish a direction based on a defined set of vectors.
