The tutor gives a nontechnical explanation of how a metal detector functions.<\/h1>\n

Watching Curse of Oak Island<\/em> on the History channel, you see them use metal detectors.<\/p>\n

How does a metal detector work? A basic explanation is this:<\/p>\n

    \n
  1. The search coil has electricity passing through it so that it emits a magnetic field.<\/li>\n
  2. A characteristic of metals (as opposed to nonmetals) is that their electrons are moved by a magnetic field.<\/li>\n
  3. As the metal object’s electrons move, they change the electromagnetic environment. It’s a kind of “rebound” effect.<\/li>\n
  4. The detector has a detection coil that senses the electromagnetic rebound broadcast from the movement of the metal’s electrons.<\/li>\n<\/ol>\n
