Linear induction motor uses electromagnetic. Electric magnetic fields are used to create two magnetic fields... one if at the bottom of the train and the other on the track. The main advantage of roller coasters is their speed, efficiency, durability, precision and controllability. The popular roller coaster system uses dozens of rotating wheels that help the train climb the hill and are arranged in two rows along the track. The wheels grip the bottom (or top) of the train between them, pushing the train forward. Of course, all roller coasters need brakes. Keep in mind: this is just a sample.

If and only the roller coaster's rails tilt, their gravity applies a downward force on the back of the roller coaster, causing it to decelerate. “As the roller coaster climbs one of the smaller hills following the initial lifting hill, its kinetic energy becomes potential energy again. In this way, the track layout constantly converts kinetic energy into potential energy and vice versa...”
