Current adjustment – the electric current can be adjusted by moving the slider.
Web camera – the camera shows the scale of the compass (magnetic latch is deflected by the magnetic field of Helmholtz coils).
Experimental values – the value of el. current is automatically loaded, angle compass needle is to be read from a webcam (Approximate value of magnetic field is shown for elementary school students who do not specify magnetic fields Helmholtz coils.)
Write values into the table – measured values are entered into the table.
Table of experimental values – the value of electric current and the angle of deflection of the compass needle (magnetic field, it is necessary to calculate the processing according to the current formula for magnetic fields Helmholtz coils).
Working with the data in the table – displaying the graph, saving the data, deleting the table.
