BEX-8508C P-type N-type Hall effect experiment apparatus
The BEX-8508C is a new Hall-effect apparatus jointly developed with Southeast University's Physics Experiment Center and awarded first prize at the twelfth national university physics-experiment instrument competition. Its open, modular, digital design exposes the N-type and P-type Hall elements, changeover switch, adapter board, and wiring for observation of signal paths and easy sample replacement. Modular power-supply, switch, electromagnetic-coil, and Hall-element assemblies simplify setup and combination. Digital interfaces for excitation current, working voltage, and current on the power-supply chassis connect to acquisition instruments and processing software for efficient measurement and analysis.
