In this work, we present a numerical simulation of the magnetic field and electrical current distribution inside a single domain YBCO disc exposed to “tooth” shaped magnetic field pulses generated by a pancake coil. The investigation of the magnetic forces acting on a zero field cooled (ZFC) disc at 77K was carried out in both static and dynamic (vertical acceleration) regimes, assuming that the superconductor is a nonlinear conductor with a “power-law” relationship between the electric field and the current. It was demonstrated that a 170 g mass disk can reach accelerations up to 2.5 km/s2 using magnetic field pulses with amplitudes of several T and rise times of tens of milliseconds
