Magnetic and Roller Coasters
Where are magnets in roller coasters?
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.
