5. Sample experiment
5.1 Measuring the magnetic field of a current-
carrying coil
Apparatus required:
1 3B NETlog TM interface U11300
1 High-current sensor U11315
1 Magnetic field sensor U11360
1 Field coil U12252
1 DC power supply unit 16 V/20 A U117361
5 Connection leads from U13802
• 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).
