In this type of gauge, a pulse generator (or tach generator) installed in the transmission measures the vehicle's speed. 2) Electronic Electronic speedometers are almost universally present in late-model cars. As the vehicle slows, the magnetic force on the aluminum ring lessens, and the spring pulls the speedometer's pointer back to zero. Attached to the aluminum ring is the pointer, which indicates the speed of the vehicle by marking the balance between these two forces. As the magnet rotates, it manipulates an aluminum ring, pulling it in the same direction as the revolving magnetic field the ring's movement, however, is counteracted by a spiral spring. This cable is directly attached to a permanent magnet in the speedometer assembly, which spins at a rate proportional to the speed of the vehicle.
