Why do people use magnets in roller coasters?

Answer 1

As far as launched coasters go, there are typically fins on the side of the coaster car. These fins pass through slits on the side of the track that have a magnetic field in them. The magnetic push or pull is what causes the train to move.

Answer 2

it's kinetic energy it works just like a regular magnet but a thousand times amplified. once the train descends or ascends the first hill all that kinetic energy comes into play along with the 3 sets of wheels.

Answer 3

Many newer Roller Coasters are launch roller coasters, immediately launching off quickly, instead of making that gradual climb up a hill letting gravity propel the roller coaster. Launch roller coaster mainly use magnets to achieve quick acceleration at the beginning of the roller coaster ride, and sometimes throughout the ride. A roller coaster may also rely on magnetic braking, where magnets slow down the roller coaster.

Answer 4

Electromagnets are used in Solenoids. The control system and the Braking system of the Roller Coaster utilize Electromagnets. The Brakes use very large solenoids to actuate them.

Answer 5

brake the trains
