Magnetic Gauge of the Displacements

Abstract

There are different methods of displacement measurement to which should be carried the mechanical methods when are used rules compasses micrometers and the mechanical standards of length There are also electrical methods when length is compared with the frequency of resonant circuit or cavity resonator whose reactive elements capacity or inductance depend on frequency There are also interference methods when displacement is compared with the wavelength of electromagnetic radiation The emission of lasers most frequently for these purposes is used In the article the new method of measurement of displacement with the aid of the Hall effect is examined
