the physics of the speedometer are fun ,one cant completely magnetize aluminum ,so the faster the magnitized iron ring spins ,which is attached to the cable ,the more of a magnetic field it makes ,and the more it partially magnetizes the outer aluminum ring and so it tries to follow the spinning iron ring and its attached in some way to the needle my speedometer staqrts to wobble at 60 miles per hour
