PRACTICE DEVICE FOR PHYSICS

摘要

SUMMARY OF THE INVENTION: slave ferromagnetic elements placed inside the ferromagnetic circular ring of longitudinal magnetization and provide a rotating magnetic field by rotating a circular ring in its plane than simulate retention output elements in the plane of rotation within the rings on their path or under the center of the ring at the expense of the balance of forces gravity, attraction, centrifugal and Lorentz forces arising. 1 yl.
