Yes, but look at this...
<i>Magnetic strength can be multiplied by up to 32 times by using steel armatures to concentrate magnetic flux. Such armatures may take the form of backing plates, channels or cups. The maximum increase in power is obtained when magnets are sandwiched between two...
That's kind of what I did. I found a magnet vendor who had a calculator which showed pull from various sized magnets at various distances. It turns out that the reason you don't see big magnetic walls is that the magnets required are not cheap at all.
Unless there is a way to make a big...
I guess the gist of my question is: Does the attractive force of the magnet diminish with distance regardless of whether a ferrous or non-ferrous material occupies that intervening distance?
Hello... I'm trying to figure out how many magnets I need to put on one side of a piece of sheet metal in order to sufficiently magnetize all the surface area of the other side to a specific attractive force to other pieces of steel in contact with the sheet. It has been too long since...
