Радіовимірювальний перетворювач магнітного поля на транзисторній структурі

Abstract

The problem of measuring the magnetic field strength of radio transmitter magnetic field on bipolar and field-effect transistors is solved. The circuit solution of radio measuring transducer is offered. It converts the magnetic field in the electrical oscillations frequency, that improves the sensitivity of the device to the intensity of the magnetic field. An experiment on proposed radio measuring transducer of the magnetic field is conducted. As a result of the experiment, we had the output frequency depending on the sensitivity of the device and the strength of the magnetic field.
