Magnetic stud finders catch on the fasteners ... Using it, we effortlessly located nails, screws, and metal studs by sliding it in an “S” pattern, back and forth, on a wall.

If you ever thought about becoming a treasure hunter this simple DIY metal detector by [mircemk] may ... The resulting oscillating magnetic field will induce eddy currents in a nearby metal ...

In short, a transmitter current attached to a wire inside the metal detector, and the coil of that wire creates a magnetic field around the detector. This magnetic field will cause an electric ...

Tiny deviations: the new metal detector looks for minute disturbances in Earth’s magnetic field. (Courtesy: iStock/muffinmaker) A compact, low-cost and low-power metal detector that can identify the ...

Metal detecting is a fun pastime, even when all you can find is a little bit of peace and a whole lot of pop tabs. [Huygens Optics] has a VLF-based metal detector that offers much more feedback ...

Metal Detector works by measuring the magnetic field around the location ... but it might help you avoid a nail in your foot or a broken vacuum cleaner. If you decide to try Metal Detector ...

there is a high risk that fine ferrous metal and fine magnetic fragments will escape even the most sensitive metal detectors. Without efficient magnets, larger pieces will be detected by the metal ...

Stanford researchers have integrated an array of tiny magnetic sensors into a silicon ... mirrors, and light detectors–that are fragile, bulky, and expensive. Wang’s biochip employs silicon ...

These antennas consist of a flat strip of metal ... concentrated magnetic field. That field allows the slot to be used as an NMR probe, in place of a coil. The detector described in the PNAS ...
