The direction in vector cross product is determined by the right hand screw rule and the right hand thumb rule.
For example :
When A×B=C, then the direction of C is right angles to the plane having vectors A and B.
*Right hand screw rule - Let the first vector be A from where the right hand screw is rotated, and towards the vector B. So the direction in which the right handed screw is rotated gives the direction of C.
*Right hand thumb rule - Here the fingers of the right hand are curled from Vector A to B. Then the direction of erect thumb will give the direction of C.
