EMF = ElectroMagnetic Force

The Jacobs Driveline Brake is an electro-magnetic supplemental braking system that is
mounted between the vehicle's transmission and rear axle. When an electric current is
fed to the brake, it passes through coils and creates a magnetic field. This magnetic field
creates drag. This drag opposes the normal rotation of the driveshaft, thereby slowing the
vehicle down.
