Compact by adjustable uniform magnetic field

Base on track, The detector and the Hall element can be adjusted on 2-axis.

Optional data acquisition interface and software. Can be upgraded to datalogging experiment system

Can be upgraded to Datalogging Experiment System

Datalogging interface and software, this can solve the problems of large amounts of data acquisition and recording in modern physics experiment, not only the acquisition time is greatly reduced, and also, the amount of data can be increased to 10X or more, and improve the accuracy of the experiment; Students shift attention from record data to data analysis, reduces the error chance in human factors.

Real-time data acquisition and analysis

Real-time dataloging means "interaction". Capstone software displays the data and curves in real-time, at the same time we can compare the results and theoretical data, helping the students understand the relationship between the variable and the results under the "interactive".

Experiments and typical data

1. When the current is constant, research the relationship between Hall voltage and magnetic field.

According to the above figure, the Hall coefficient and mobility can be measured.

2. When the magnetic field is constant, research the relationship between Hall voltage and Hall current.

According to the above figure, the Hall coefficient and carrier density can be measured.

Note: the datas are tested with PASCO sensor. If you need sensors, you can consult your local PASCO Reseller for purchase.
