1. Activity points. 70. The limit of a good metal detector is about 30 cm in soil with low mineralisation for 1 Euro coin. The equivalent of this is about 40- 45 cm air drtrction. This is impossible for 90% of the mass produced detectors. Building a deep detector is an art.
Metal Detector Circuit: An Introduction Guide
Metal detector circuits use an oscillator that produces alternating currents. An eddy current passes through the metal when active. Hence, the current produced passes through a coil. Doing this creates an alternating magnetic field. The magnetic field attracts the metal closets to the coil. As a result, the metal changes the magnetic field ...
