Does metal detector detect magnets?

The walkthrough metal detector or hand held detector wand detecting matals by the frequency domain of metals, if the security door seting the magnets frequency, then it can detect the magnets. read more

No metal detectors don’t detect magnets. This is because metal detectors rely on eddy currents that are induced in metals by a coil driven by a radio frequency oscillator. These induced currents in turn produce a small magnetic field that can be sensed. read more

How A Metal Detector Works The operation of metal detectors is based upon the principles of electromagnetic induction. Metal detectors contain one or more inductor coils that are used to interact with metallic elements on the ground. read more
