They clearly state that Newtons are per meter and watts are per second, but there seems to be a clear relationship.

What other info is needed? Here's what is listed on this magnet:
http://www.kjmagnetics.com/proddetail.asp?prod=DY0X0
Pull Force: 231.55 lbs
Surface Field: 7100 Gauss
Brmax: 13,200 Gauss
BHmax: 42 MGOe
With the above magnet,
if 20 lbs. equals 100 Newtons
then,
231 lbs...
Can anyone help me determine how much force is created when a one tesla permanent magnet is allowed to make contact with a flat piece of iron. The distance that this size magnet can be released and will be drawn to the iron is about 3 centimeters. Is there any way to express this force in joules...
