It has been found in certain applications that the steel take-off ring actually improves the separation. The ring has a broad flat surface adjacent to the magnetic pole to receive and carry the flux built up by the magnet. The sides are shaped to form a parabolic curve ending in a defined peak where the concentrated field is produced.Web

So the magnitude of the force is equal to the current-- 2 amperes-- times the magnitude of the distance-- times 10 meters-- times the magnitude of the magnetic field. That's 6 times 10 to the minus 4 teslas. And then when you take the cross product, you take the sine of the theta between these two vectors.Web
