Lorentz Force Law: A mathematical equation that describes how an electric charge experiences both electric and magnetic forces in an electromagnetic field.
Right-hand Rule for Cross Products: A rule used to determine the direction of the resulting force when two vectors (velocity and magnetic field) are crossed.
Centripetal Motion: Circular motion caused by an inward-directed net force acting perpendicular to an object's velocity.
