Why a high input impedance device is generally needed to measure the hall voltage

Answers

Answered by Selvasiddharth

8

The reason for low current is very low magnetic coupling with between thehall effect sensor and the magnetic field source. ... To minimize this current, a high impedance input device(amplifier) must be used. High impedance ensures that minimum possible current is sourced by the sensor and accuracy is maintained.
