Instead, drop tower rides use magnetic brakes in conjunction with hydraulic cylinders or air-pressurized brakes. Magnetic brakes work based on electromagnetic induction, a system that can be explained using Lenz's law.

Coasters stop by the use of many types of brakes. A traditional method of stopping a coaster train is by fin brakes. Fins are attached to the undercarriage of the coaster car and slide into a series of clamps attached to the track.
1. Drop Towers: Drop towers are thrilling rides that take riders to great heights and drop them at high speed. Unfortunately, these rides can also cause injuries such as neck injuries, back injuries, and fractures due to the sudden jolt of the ride.
And as Lenz's law states, that magnetic field opposes the motion of the magnets. As a result, the magnetic field pushes up against the seat, causing the cart to slow down. This is how a drop tower ride's magnetic brakes work. These magnetic brakes are used with hydraulic cylinders to further slow the falling cart down.
While commercial flights exert only very minimal positive and negative G-forces on passengers, several orders of magnitude greater are the G-forces experienced by astronauts, fighter pilots and stunt pilots. These types of pilots can experience brief periods of extreme forces of nine and 10 Gs.
