How can I let the metal on my body escape the scanning of the metal detector? The metal detector doesn't ring!

The metal detector uses the principle of electromagnetic induction to generate a rapidly changing magnetic field by using a coil with alternating current. This magnetic field can induce eddy currents in metal objects. The eddy current will produce a magnetic field, which will affect the original magnetic field and cause the detector to sing.

Answer: Theoretically, a strong electric field can interfere. Or put the metal in a box made of magnets to reduce the chance of being found.
