0. Many roller coasters use magnetic brakes to slow the train at the end of its run. A conducting plate on the train passes by powerful magnets fixed on the track. a. Explain the principle behind this magnetic braking. b. The system needs an ordinary friction-based brake to bring the train to a full stop. Explain why the magnetic brake is not very efficient when the train is moving slowly
