Remote Measurement of Magnetic Field Distribution in the Solenoid
This paper presented an innovative approach to implement physics experiment by remote measurement system. In the experiment of magnetic field distribution in the solenoid, a two channel programmable current source was adopted, one channel of the programmable current source was used to incentive the solenoid to produce magnetic field and the other was used for the Hall probe to generate Hall voltage. The Hall probe was controlled by a step motor to different positions of the solenoid. The Hall voltage and the position curve were obtained by the measurement system showed the magnetic field distribution of the solenoid. The entire experiment was done via the internet to realize the remote experiment.
