Electromagnetic Field Emitted by Electronic Laboratory Instruments

Abstract

In the article the need for research the electromagnetic field emitted by electronic laboratory instruments is shown and justified. Theoretical considerations about the essence of the electromagnetic field, its sources, and the possibilities of the electromagnetic field were surrounded by two devices commonly used in the electronics laboratory: a function generator and a laboratory power supply. The tests have shown that laboratory instruments emit electromagnetic waves over a large frequency range from 50 Hz to 10 kHz. The intensity of the electromagnetic field around the tested devices is within the normal range, and is maximum value for the functional generator is 218.6 V/m (electric component) and 44.15 T (magnetic component), and for the power supply – 221 V/m and 37.05 T.
