| Abstract |
It is known that rapidly alternating forces acting on a mechanical or
electromechanical system can substantially affect its dynamic properties,
e.g., produce new equilibria, alter the properties of existing equilibria,
cause self-induced vibrations, etc. We show how the action of rapidly
oscillating electromagnetic forces can be used to devise a new passive
magnetic suspension of inductor type. In the simplest case, the suspension
is a system of two rings with a common vertical axis, one of the rings
being fixed and the other being free. The rings are powered with
alternating current, which gives rise to stable equilibria in the
gravitational field. Under certain conditions, such a suspension can serve
as an alternative to a superconducting suspension in a constant magnetic
field, for which the stability of the equilibrium is known as the
"magnetic potential well" effect [1]. |
