Compass Helps Locate Covered Switch Boxes

00:26:44

If wall switch boxes or outlets are plastered or covered over you can use a magnetic compass to help locate them.  I tried magnetic compass over wall switches and outlets, most of them  facing north.  I would get about 25 to 30 degree deflection when I was very near the outlet box.  All had power on, so I do not know if simply metal boxes would be enough to show on compass needle?
