Set up the experiment according to Fig. 1
In order to build up a measurable magnetic field, a
current of up to 10 A must flow into the field coil.
At 10 A, the high-current sensor supplies a voltage
of 50 mV which is proportional to the current. The
selected measurement range is 200 mV at the em-
ployed voltage input of the interface.
•
Connect the magnetic field sensor to the inter-
face.
•
Increase the current in the field coil from 0 to
10 A in steps of 0.5 A and record the corre-
sponding flux density (Fig. 2).
