PKI's Drop Zone, and other rides like it, are said to utilize "permanent magnetic braking" systems. My question is this: Are these electromagnets? Do they require surges of electricity to stop the vehicle, such as a propulsion system on a ride such as FoF?
If they do, does the ride "store" the amount of energy needed to stop the vehicle in case of a power failure?

You can see this in action on The Beast. If the train is lightly loaded, then when the train hits the mid-course trim brake it will very quickly slow down (brick-wall style) to the exit speed and maintain that same speed until it comes out of the brakes. A heavier train will slow down more gradually (because it has more energy and is therefore harder to slow) but will come out of the brakes at the same speed as the lightweight train.
In contrast, with friction brakes, a lightly loaded train will lose too much speed to the brakes, while a heavily loaded train might not lose enough at a given pressure setting. The action of the magnetic brakes ends up being more consistent.
