Some of the devices use magnetic fields to detect nail heads in the studs or to scan for wires. By measuring the electrostatic field of a wall and detect slight differences in the flow of electrons stud finders detect the relative change in density and thereby studs showing the best place to drive that nail.

How does a magnetic stud finder work. How magnetic stud finders work the very first stud finders were magnetic in nature. Magnetic stud detectors set the stage for the explosion of other technologies. Here is how you can use a magnetic stud finder step 1. Magnetic stud detectors use magnets to locate metal in the walling material because the magnet is attracted to the metal. Dangling the magnet along a wall revealed all the nails and screws in or beneath the drywall. The attraction grows stronger as the magnet gets closer to the metal in the walling.
They existed in the form of tiny magnetized finders that got drawn to screws or nails behind the wall. Studs are placed within a range of 16 inches or 24 inches. Magnetic stud finders how they work. Step 2. The magnet would help you find nails that had been driven into a stud. The magnet technique is slow.
Grab magnet from fridge hang with dental floss i grabbed a plain magnet from the refrigerator and tied a piece of dental floss to it any fine string or thread would work. Find out the exact position where the top. So this is how a stud finder works. Step 3. Although some studs are made out of wood the magnetic stud finder can still locate them by detecting the metal nails or screws that are lodged in the beams. Stationary magnetic stud sensors run on a small immovable magnet to detect.
This field produces its own variable magnetic flux in a metallic object found at an accessible distance. The first technique works but it damages the wall. They give you an amazingly accurate view into the wall and show you exactly where each stud is. Once i marked a few with a pencil it was obvious where the studs were. Electronic stud finders changed all that. To find a stud all you needed to do was to find a screw or nail.
The alternating current of the device creates a non constant magnetic field which is subject to change. 8 things to consider about how to use a magnetic stud finder. Just like a metal detector the magnetic stud finder actually locates the studs support beams within the walls by detecting the beam itself if it is made out of metal. Stationary magnetic stud finders. Before there were stud finders either you pounded a small nail into the wall until you hit a stud or you used a small pivoting magnet. Hence your target area will be to look for a stud.
Make a selection of the place where you want to hang the item. The strongest attraction point if due to a metal fastener in the wall should indicate the location of a stud.
