Magnetic Gauge of the Displacements
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.
