China Wholesale Hall Effect Factory – LEEM-1 Helmholtz Coil Magnetic Field Apparatus – Labor Detail:

Helmholtz coil magnetic field measurement is one of the important experiments in physics experiment syllabus of comprehensive universities and engineering colleges. The experiment can learn and master the measurement method of weak magnetic field, prove the superposition principle of magnetic field, and describe the distribution of magnetic field according to the teaching requirements. This instrument uses the advanced 95A integrated Hall sensor as the detector, uses the DC voltmeter to measure the output voltage of the sensor, and detects the magnetic field produced by the Helmholtz coil. The measurement accuracy is much better than that of the detection coil. The instrument is reliable, and the experimental content is rich.

Experimental project

1. Study the measurement method of weak magnetic field;

2. Measure the magnetic field distribution on the central axis of Helmholtz coil.

3. Verify the principle of magnetic field superposition;
