Question:
Where are magnets in roller coasters?


Replies:
There are many places that magnetics may be used in roller coasters. Uses include the lift motors, gate closures, proximity sensors, safety interlocks, and computers. Some roller coasters have magnetic propulsion and/or magnetic braking. Some roller coasters need cooling fans (another type of motor) for electrical distribution panels and electronics. Magnets are used in the microphones and speakers for announcements and music. In some cases, there are recorded announcements on magnetic media. Test equipment for safety checks also use magnetics.
