Question

Briefly discuss the physical origin of hall effect

Answer 1

For clarity, the original effect is sometimes called the ordinary Hall effect to distinguish it from other "Hall effects" which have different physical mechanisms. 

hope it helps

Answer 2

The physical origin of the hall effect:

• In 1879, the Hall Effect was developed by Edwin Herbert Hall
• When a current-carrying conductor or a semiconductor is exposed to a perpendicular magnetic field, the Hall Effect asserts that a voltage can be measured at a right angle to the current direction.
• The Hall Effect is a method of obtaining a quantifiable voltage.
