Right-hand rule and vector cross product

Right-hand rule for vector product, with examples of the unit vectors of a cartesian coordinate system, the force due to a magnetic field, as well as the rotation vector, angular momentum vector, magnetic momentum and magnetic field due to a current.
Also see other figures under the “vectors” tag: vector sum rule, scalar production, or the divergence and curl of vector fields.
