It is when opposite ends of the magnets create a magnetic field that makes the object levitate.
Electromagnetic Suspension (EMS)
Brand new hydraulic shocks that run an electric generator. The shock action pumps the motor impeller and makes electricity. Bose just came out with electromagnetic suspension. For a truck you might get some excess energy output with magnetic/electromagnetic suspension with coils picking up the moving magnetic flux from the suspension cylinders and making power. Magnetic field moving past a wire is how a generator works. Put magnets on the moving rods and wrap it with coils of solid copper wire. A linear generator.
Toothpaste is not a simple suspension but a Colloid suspension. A Colloid suspension is a suspension that has microscopic particles suspended in another substance.
A suspension has large particles that settle out on standing.
A Maglev (magnetic Levitation) runs in a new technology. Maglev work by magnets. There are large rotating magnets built onto the sides of the track and train. This causes the Maglevs to levitate. This is possible by electromagnetic suspension.
The cables in the suspension bridge supports the suspension bridge.
