Abstract

Predstavljene su dvije najčešće izvedbe magnetometara i princip njihovog rada. Nabrojeni su sustavi pomoću kojih se stvara homogeno magnetsko polje. Postavljen je i simuliran matematički model općenitog Helmholtzovog svitka. Zbog postojanja parazitnih elemenata struja koja ulazi u sustav, struja koja se mjeri i struja koja stvara magnetsko polje nisu iste. Izvedena je idealna i realna nadomjesna shema Helmholtzovih svitaka. Izvedene su funkcije struja u ovisnosti o frekvenciji. Određene su pogreške između struje mjerene na shuntu i struje idealne nadomjesne sheme. Proučen je rad sustava oko rezonantne frekvencije. Predstavljene su granične razine gustoće magnetskog polja.

Abstract (english)

Two most common designs for magnetometers and way they work are presented.
Systems which produce homogeneous magnetic field are listed. Mathematical model is
set up and simulated to define homogeneous part of magnetic field for general system
Helmholtz coils. Due to the existence of parasitic elements, the current which enters
system, current to be measured and the current that creates a magnetic field are not
the same. Function of all these currents is derived with respect to frequency. Ideal
and realistic equivalent circuit of Helmholtz coils is derived. Certain errors between
measured current at the shunt and ideal equivalent current are defined. Operation of the
system around resonant frequency is analyzed. Marginal level density of the magnetic
field is presented.
