Main Question or Discussion Point
I was inquiring about how much force will a 1000 lb pull force electromagnet pull at 4-6 inches away from the magnet
Yes, if the magnet is flat, and the 1000 lb pull is at the flat surface, you've blown my calculation out of the water :tongue:Yea, my first thought was to attempt a simple 1/r^2 solution but I decided the likely geometry of a magnet would be flat pole pieces. The approximation to a sphere is just too wild for my taste.
I should imagine this is a ring magnet anyway. The field would be highly localised.
