The paper presents numerical simulations of the magnetic forces acting on a moving magnet due to the eddy currents of a Lorentz force eddy current testing system. Numerical simulations of quasi-static and transient approaches are accompanied by some asymptotic analytical solu-tion and the operating linearity range of the Lorentz force sensor is estimated.
