In the experiment: Biot-Savart law, the profile of the magnetic flux density B of current-carrying conductor loops with different radii R and the magnetic flux density of a straight wire is determined and discussed.

Both, the position of a magnetic field sensor, i.e. the distance z to the conductor loop plane, and the magnetic flux density B are measured simultaneously. This is realized via the remote controlled positioning system PS400 (article no. 1023719) and the magnetic field sensor (article no. 1021798). The acquired digital data are automatically processed and visualized in the Coach7 software, so that the profile of the magnetic flux density B(z) is graphically displayed simultaneously as the sensor passes through the magnetic field.

The Biot-Savart law: B(z) = µ0 I / 2  * 2 / ( )3/2 is discussed and verified via the following sub-experiments:
  1. Profile of the magnetic flux density B(z) of a conductor loop with radius R at given current I.
  2. Dependence of the magnetic flux density B of a conductor loop with radius R on the current I in the plane of the conductor loop (z=0).
  3. Determination of the magnetic field constant μ0

Advantages when using the PS400 Remote Controlled Positioning System:
The used PS400 positioning system (article no. 1023719) ensures fast, precise and reproducible measurement of the magnetic field generated by the conductor loop.
 
Advantage of computer-aided experimentation:
Besides the advantage of instantaneous visualization of the measurement, the measurement is also very fast (< 30 s). Therefore, varying the experimental conditions (e.g. conductor loops with different radii or different currents) is easy and quick to implement.
 
Variants of digital data processing:
Variant 1: (PC/Tablet)
2 x 1021514 Sensor Cable
1 x 1022284 WiLab
1 x Software License Coach7
or
Variant 2: (Data-Logger VinciLab)
2 x 1021514 Sensor Cable

Note:
Alternatively, the position of the carriage of the positioning system can be read out with the output voltage VOut. Thus, monitoring systems or software of other suppliers can acquire the position information by using a suitable voltage sensor.
