Electromagnetic Field Detector

Electromagnetic field detector (also known as gaussmeter) is an instrument for measuring magnetic induction intensity based on the Hall effect principle. It consists of a Hall probe and a measuring instrument. The Hall probe generates Hall voltage due to the Hall effect in a magnetic field. After measuring the Hall voltage, the magnitude of the magnetic induction intensity can be determined based on the Hall voltage formula and the known Hall coefficient. The reading of the electromagnetic field detector is in Gauss or Kilogauss.

Principle of Electromagnetic Field Detector

The working principle of the gauss meter is based on the electromagnetic induction method, which uses the induced electromotive force of the conductor magnetic flux to measure and determine the strength of the magnetic field. Specifically, the Tesla meter moves the detector in the measurement area, measures the change in the detector's induced magnetic flux density in the longitudinal and transverse directions, and records it.

Design of Electromagnetic Field Detector

Electromagnetic field detector usually consists of two parts : a detector and a display. The detector is an induction coil placed in the measurement area, while the display is a digital electronic oscilloscope that displays the measurement results.

When designing an electromagnetic field detector, some key factors need to be considered, such as the shape, size and material of the induction coil. These factors determine the measurement range, accuracy and sensitivity of the emf detector.
