Many newer roller coasters have an unpredictable start, immediately launching off quickly, instead of making that gradual climb up a hill before sending us on a terrific series of drops and hills. This new launch style
The type of magnets used in a roller coaster may vary, but the roller coaster depends upon both the negative and positive abilities of magnets. The quick launch of a roller coaster is often due to magnetic propulsion. This relies on magnets repelling rather than attracting one another. Estimates with very strong magnets suggest such propulsion could send a roller coaster up to 100 mph in a matter of seconds

A hyper coaster, or supercoaster, is an
As well as long drops the hyper coaster may also feature misty tunnels, and quick loops before dropping again. First hyper coasters cars were seated on the track like most steel roller coasters. Now cars may be atop the track, and offer a standing or sitting feature.
Some roller coasters now have hanging seats, which can actually flip around the track as the car is in motion, causing multiple inversions. They also add more thrill since the feet dangle without support, and seem dangerously close to the track. Roller coaster purists, however, say one cannot define an inversion coaster as a hyper coaster. So traditionally, the hyper coaster cannot loop the track, though it can turn upside down while remaining on one side of the track.

Steel allows looping design elements that wood does not. Wood maintains many sub accelerations on sway between bents that steel does not. There are also differences on cost and maintenance. The original cost of a steel may be more than wood, but the maintenance might be less. Over the long haul, the total costs are similar.
