the pipe when the magnet falls through. See also Dynamic braking - either rheostatic (dissipating the train's energy as heat in resistor banks within the train, or regenerative where the energy is returned to the electrical supply system) Electromagnetic brakes (or electro-mechanical brakes) – use the magnetic force to press the brake mechanically on the rail Linear induction motor can be used as a regenerative brake Notes References Brakes Electromagnetic components Electrodynamics Railway brakes Physics experiments Electromagnetic brakes and clutches fr:Frein à courants de Foucault nl:Wervelstroomrem
