Introduction:

The sensing component of Magnetic Induction Intensity Sensor is a very small semiconductor Hall slice. A stable current is provided by sensor circuit. When there is a magnetic field which is vertical to the Hall slice, potential difference will be formed at both end of Hall slice.
The working principle of Hall slice is the charge carrier in semiconductor making accelerated movement due to electric field. Applied by magnetic field, the charge carrier will be deflected by Lorentz force. Charge will be accumulated on both sides of Hall slice. Hall potential difference will be formed eventually. When input current is stable, Hall potential difference is direct proportional to magnetic induction intensity. By using amplifying circuit to amplify Hall potential, the magnetic induction intensity can be measured.

The Hall slice is fixed in the front of probe as shown in Fig.1. Keep the axial of probe pointing same direction of magnetic field. Otherwise the value of the magnetic induction it measures is only the projection component of the magnetic field in the direction of end surface.
Calibration:
Calibration is not required.
Usage:
It is very easy to use the Magnetic Induction Intensity Sensor. You can measure magnetic induction intensity as long as finish installing. Actually, the Hall slice is fixed near inner surface in the front end of probe. It is 2.5mm away from outer surface. This sensor can only measure the magnetic field parallel to the axial of probe. When measuring, select optimum direction and position shown in figure below.
The impact of temperature on Hall voltage and internal resistance is very small. In general experiments, the effect of temperature can be ignored.

Typical experiment:

• Measure the magnetic field of permanent magnet
• Measure the magnetic field of Helmholtz coil
• Measure the axial magnetic field of electrified solenoid
• Measure the magnetic field around the electrified wire

Experimental case:
Measure the axial magnetic field of electrified solenoid:

Experimental procedures:
1. Connect experiment apparatus.
2. Open SWR iLab v8.0. Click 'New' to create new experimental template.
3. Click 'New page' and select the sixth template to create new folder. 
4. Click 'add line' to add 'Magnetic Field-Distance' coordinate.
4. Power on the solenoid. Put the sensor 5cm away from the side of solenoid axis.
5. Click the 'Manually' button to collect the experimental data.
6. Move the sensor 1 more cm towards the other side of solenoid. Click 'Manually' button to collect experimental data.
7. Repeat procedure 6 till the probe is 5 cm away from the other side of solenoid. Data collecting is completed.
8. Click 'Stop' button to complete data acquisition.
9. Clear up experimental apparatus                                                                                                                                          Notes:
1. This Magnetic Induction Intensity Sensor is not suitable for measuring very small magnetic field such as geomagnetic field.
2. In the magnetic field to be measured, there should be no iron or magnetic object because it will change the magnetic field distribution. 
3. When carrying out electric field experiment, check the low voltage power source if the output is stable. The magnetic field will vary if power source is not stable.
4. This sensor is not water proof. Be careful with that.
