LEEM-5 Hall Effect Experimental Apparatus

Experiments
1. learning the principle of Hall effect and mapping the curve of Hall element.
2. learning to measure the magnetic induction strength B using the Hall effect.
3.Measure the magnetic field distribution of the electromagnet coil.
Main technical parameters
1. Excitation constant current source: 0 ~ 1.2A continuously adjustable, fineness <1mA, 3 and a half LED digital display.
2. Sample working current 0 ~ 5mA, stability <10-5, DC millivolt meter 0 ~ 20mV, resolution 10µV.
3. Switching current direction with high quality reversing switch, avoiding the problem of easy damage of relay and common switch.
4.Produce magnetic field with electromagnet, current size and magnetic field strength can be customized.
