A conventional electromagnetic coil launcher has some inherent problems and technical limitations. We present a novel multipole field electromagnetic launcher based on eddy-current catapult and multipole induction acceleration. We introduce the operation principle and conception model. We analyze the electromagnetic acceleration force of eddy-current catapult and induction acceleration. We establish the system circuit equation and dynamics equation. Using electromagnetic field finite-element analysis coupling with the circuit, we simulate and compute the transient launch process of multipole field electromagnetic launcher. The simulation result indicates that the multipole field electromagnetic launcher has the potential of developing huge thrust force, large driven mass, supervelocity launch, and steady maglev.
