Do metal detectors work

Answer 1

The metal detector is device to spot hidden metal. It works on Th principle of disturbance in magnetic filed. The detector has magnetic coil through which an alternating current is passed producing magnetic field. When the hidden metal comes within the range of this field then the eddy current is produced in this metal creating its own magnetic field which is detected by metal detector.

Answer 2

The more you spend on one the better it'll work, (et: find more stuff.).. I bought one for ,like, $400.00 and it works fine, I find lots of stuff at the beach. Coins, watches, rings, things that came off necklaces and bracelets. And ,of course, those pull-tabs and gum wrappers and bottle caps. I've yet to find that diamond ring or gold watch, but I'm still looking and hoping. It's great fun and good exercize,, anyway you look at it, gets ya out of the house off the computer. I live just 12 miles from the (ocean) beach so i havent tried using it anywhere else.

Answer 3

Absolutely. Although minerals in water tend to disrupt the magnetic signature so depth is shortened dramatically in water with high iron content. Also detectors with metal specific detection may be slightly less reliable

Answer 4

Magnetism enables metal detectors. Electrically induced magnetism can be specifically broadcast and when recieved can be determined for distrubance (metal) and a sound is played (generally). Electricity is needed as is magnetism. Those two things are why metal detectors work.
