Downsizing of superconductive electromagnetic engine
Cancelling a difficult point of the downsizing
The superconductive electromagnetic engine functions by the magnetic field of ripple current being partial.
However, it is thought that the being partial is cancelled by the overlapping of the magnetic fluxes of the ripple current when the size of the superconductive electromagnetic engine is too small.
In that case, it is thought that they may use magnetic shielding.
If they make the magnetic shielding stopping the magnetic fluxes from invading the center part of the superconductive electromagnetic engine, the effect of the overlapping will be cancelled.
For a method of the magnetic shielding, superconductor will be good.
