Abstract
This paper discusses the magnetic drag force resulting from the relative motion of a
permanent magnet moving along a finite dimensional conducting plate. The image method with
imaginary eddy currents is investigated. Boundary conditions are established to ensure that the eddy
currents vanished at the boundaries of the conducting plate. Magnetic drag force is computed based
on the eddy current distributions using Lorentz force law. A test system is built to demonstrate the
magnetic brakes arose from the electromagnetic interactions.
