The TEAM 28 problem introduces an axisymmetric electrodynamic levitation device which consists of a conducting plate over two stranded coils. The aim is to determine the dynamic characteristics of the levitating plate (after some damped oscillations, the plate attains a stationary levitation height). A coupled solution of the electromagnetic and the mechanical problem is necessary.
