A Study Of The Magnetic Induction-repulsion Accelerator

The acceleration of a disk or ring shaped conductor by a similarly shaped drive coil has been the subject of more than a dozen reports over the past 25 years, but these reports have mostly been concerned with applications rather than the controlling relationships and the physical events in the propulsion process. In this paper, four aspects of the propulsion are studied. These are: an overall equation which relates all the main parameters including the mass of the accelerated disk; the effect of resistance; the importance of the initial induction into the disk; and the effect of the shape of the magnetic field. The studies suggest that an efficiency of about 30% is achievable in practice and that it is probably not worthwhile trying to implement some theoretical ways of raising the efficiency.
