Right-Hand Rule for Vector Cross Product - Visual Guide #2115394 (License: Personal Use)

This diagram demonstrates the right-hand rule for computing the cross product of two 3D vectors, a and b. The index finger aligns with vector a (purple), the middle finger with vector b (green), and the thumb points in the direction of the resulting vector a × b (blue arrow). The hand is shown in a natural pose to reinforce muscle-memory learning for vector orientation.

Used in physics, engineering, and mathematics education to teach 3D vector operations; commonly appears in textbooks, lecture slides, and online tutorials explaining torque, angular momentum, or magnetic force direction.
