How do stud finders work?

Whether you are hanging pictures, putting up a new set of shelves or getting ready to start an addition, knowing where the studs are in a wall can be extremely handy! 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. The magnet would help you find nails that had been driven into a stud.

The first technique works, but it damages the wall. The magnet technique is slow. Electronic stud finders changed all that.

They give you an amazingly accurate view into the wall and show you exactly where each stud is. In a way, these stud finders are like a touch switch on a touch-sensitive lamp. They are using changes in capacitance to sense where the stud is.

When the plate inside the stud finder is over wall board, it will sense one.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
