Principle and Working:
When a conductor through which current is flowing, is placed in the magnetic field, a potential difference is generated between two opposite edges of the conductor in the direction mutually perpendicular to both the field and the conductor. This potential developed is Hall voltage & the phenomenon is called Hall effect.
In the present setup, the crystal mount on PCB is placed perpendicular to the pole pieces. Magnetic field is produced by electromagnet operated by 0-16V, 5A power supply. Field intensity measured by gauss meter with radial gauss probe. A constant current is passing through the crystal and hall voltage measured via multimeter.
