This post discuss Hall Effect Principle, its history, theory, applications and mathematical expressions for Hall Voltage, Hall Coefficient, Hall Mobility etc

Hall effect sensors are devices that detect the presence of a magnetic field. They operate based on the Hall effect, which is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor, and a magnetic field perpendicular to the current. Hall Effect Sensors are extensively used in various fields, this post will discuss working, types, applications, advantages, & disadvantages.

Clamp Meter (Tong Tester) is one of the most useful test equipment. This post will discuss Tong Tester types, Operating Principle and how to operate it.
