A voltage measuring at 90 degrees from the current’s direction. Based on the theories, it is when the conductive plate connects to a battery. The magnetic field is disrupted and negatively charged electrons can be shifted towards one direction. The purpose behind a Hall Effect current sensor is to determine if a material is an insulator or a semiconductor. This video illustrates the science as well as the use for the application of Hall Effect sensors to different devices.

A Hall Effect sensor is a device that measures the power of magnetic fields. It determines the speed of the electric field, and triggers the charge to move between two surfaces. The amount of electrical charge that is generated is directly proportional to the magnitude of the magnetic field flowing over the conductor. The technology is used on speedometers for cars, printers, and electronic ignition systems. The technology is also applied to fluid flow and pressure sensors. These sensors are used primarily in the automotive industry with application in indicators for fuel levels. szxdepsfcm.
