Closed-loop control Helmholtz coil system

I. Closed-loop control principle

The closed-loop control of the Helmholtz coil system, can automatically control the magnetic field generation. The system is composed of connected fluxgate meter, Helmholtz coils, power supply, computer, which formed a set of closed-loop control system. The system uses fluxgate meter to achieve the actual magnetic field, which will forward measurement signal back to the computer, after software processing, directly the computer control coil power output constant current size, in order to achieve the geomagnetic field compensation or the vector magnetic field required by the user, the user can set the magnetic field required directly by software. Helmholtz coil is equipped with a vertically adjustable platform, and adjusting the position of the test sample.

III. Software interface

XYZ three vactors real measurement and display and XYZ resultant vector size, and graphically display intersection angle of the resultant vector.
The control software can automatically set, control and display the magnetic field size, and can record the magnetic field values ​​for a long time. Easy to operate, clear display.
