[QUOTE="jrmichler, post: 5995701, member: 638574"] A magnet that produces a 1 T field will pull 58 PSI on a steel surface. That's pounds per square inch of pole area contacting the surface. It is very roughly the strength of a neodymium iron boron magnet in contact with a thick piece of steel. A neo magnet of size 1" X 2" X 2" is too strong to safely hold in your hand if there is any steel or other neo magnets nearby. The pull force is proportional to the square of the field strength, so a 3 T magnet will pull 9 X 58 = 522 PSI. I had to study up on this some years ago when I designed an electromagnet to pull 1600 lbs force through a 1/4" air gap. And was amazed when it actually worked according to the calculations. [/QUOTE]
