Abstract
A contact free magnetic bearing in which a magnetic body is disposed betw a pair of opposed magnetic poles so that the magnetic field between the poles is in supporting relation to the magnetic member disposed therebetween. Deviation of the magnetic member relative to the magnetized poles is detected and the strength of the magnetic field between each of the poles of the magnetic member is varied to establish influences acting between the poles and the magnetic member tending to restore the condition of equilibrium.
