What is the name for the phenomenon where a gyroscope's axis moves perpendicular to the direction of an applied torque?

Answer

Precession

When an external torque is applied to a spinning gyroscope, the axis moves counterintuitively at a right angle to the direction of the applied torque, a change known as precession.
