In [[mathematics]] and [[physics]], the '''right-hand rule''' is a [[Convention (norm)|convention]] and a [[mnemonic]], utilized to define the [[orientation (vector space)|orientation]] of [[Cartesian coordinate system|axes]] in [[three-dimensional space]] and to determine the direction of the [[cross product]] of two [[Euclidean vector|vectors]], as well as to establish the direction of the force on a [[Electric current|current-carrying conductor]] in a [[magnetic field]]. 
 
The various right- and left-hand rules arise from the fact that the three axes of three-dimensional space have two possible orientations. This can be seen by holding your hands together with palms up and fingers curled. If the curl of the fingers represents a movement from the first or x-axis to the second or y-axis, then the third or z-axis can point along either right thumb or left thumb.
