Active controlled Magnetic Bearings are known as a poor technology and engineering. This paper describes how easy it is that suspense an object by the magnetic pull force, the process of development of the Simple AMB bears a rotor of 120kg on 16500rpm is shown. The key technology of the simple AMB is detection of the relative velocity between the rotor and bearing, is described in this paper, two way of detectors are experimented, the one is variable capacitance and the other is variable reluctance. The newly designed "AMB" was invented a half century ago and experimented on the various instruments by the writer, however the writer hasn't applied a patent concern to it because a patent lives only a 20 years on the civilized nations but on Unsettled Society About patent handlings, writer has obtained patents just on the needs usually.
