Hall Effect Measurement Kit
Discovered by Edwin Hall in 1879, the Hall effect is one of the foundational experiments in physics. It provides a powerful way to illustrate electromagnetic laws (Maxwell’s equations) and explore material properties such as carrier type, concentration, and mobility.
Our Hall effect measurement kit is designed for intuitive, room-temperature experiments — reaching magnetic fields up to 0.25 Tesla using a USB-powered supply.
Included in the kit:
Hall-effect measurement station
The station is a passive module featuring a split pulsed magnet that can produce magnetic fields up to about 0.25 T when driven by our JANUS current source.
Pulsed current source JANUS
JANUS is a compact, USB‑powered, bipolar capacitive power supply designed for driving miniature pulsed magnets. It features a 4 mF capacitor bank that can be charged to below 50 V, providing up to 5 J of stored energy.
Precision current source
When measuring electrical transport, it is essential to inject a well‑defined and stable current into the sample. If the sample impedance changes rapidly during the experiment, the current source must track these variations to maintain a constant current. In many situations—such as Hall measurements—it must also be possible to reverse the current easily to eliminate induced or parasitic effects
