1. The problem statement, all variables and given/known data Hi, I am trying to calculate the current and magnetic field strength needed to pick up a 0.3125 lb. piece of a channel lock plier made of ferritic stainless steel (they have a soft magnetic component) on its y axis (on the lighter part of the piece) at an 80 degree angle. The magnet would be located 9.36 in. above the piece of steel. 2. Relevant equations Fb = ILB Fb = qvB B = ([tex]\mu[/tex]0I)/[4pi(y)] 3. The attempt at a solution I drew a freebody diagram and found that the magnetic force needed to pick up the piece of channel lock plier would be 12.3N. I did more research and found that a magnetic field force would only be exerted on moving charge particles. Now I am stumped on how to find the current and magnetic field strength without knowing the other.
