Hall Effect

When a conductor crossed by current is placed in a magnetic field, a potential difference is developed across the conductor
in the direction perpendicular to the field and to the conductor
itself.
The developed potential is called Hall voltage and this phenomenon is called Hall effect.
A complete setup includes : a variable current source of 20mA, 2 coils and U-shaped magnetic core with yoke fixed onto a base.
The equipment also includes some supports for keeping germanium crystals mounted on PCB.
The set can be completed with power supply unit, a digital multimeter, data logger, and with transverse magnetic field sensor.

TRAINING PROGRAM
