This paper presentation explores the working principle of eddy current brake mechanism, which can be analyzed by Maxwell 3D Transient solver. An eddy current brake, like a conventional friction brake, is responsible for slowing an object, such as a train or a roller coaster etc. Unlike the friction brakes, which apply pressure on two separate objects, eddy current brakes slow an object by creating eddy currents through electromagnetic induction which create resistance, and in turn either heat

... electricity. In this paper, linear Halfback magnetized mover is applied to eddy current braking system for high speed. For such a breaker, we give analytical formulas considering end effects for its magnetic field, eddy current distribution, forces according to the secondary relative permeability, and conductivity. The results given here are purely analytic & applicable. INTRODUCTION The term "EDDY" Focault Bae J. S.(2004) found that when magnetic flux linked with a metallic conductor changes, induced currents are set up in the conductor in the form of closed loops. These currents look like eddies or whirl pools and likewise are known as eddy currents. They are also known as Focault's Current.
