The Magnitude of magnetic force

  1. Jun 14, 2013 #1

    I am have a piece of iron that weighs 0.2 Kg, and I want to attract it vertically (against gravity) with a magnet from a distance of 0.3 M.
    I started looking online on different magnet providers, they provide information such as the "Magnetic Face area: 20 x 30mm, Thickness: 10mm, Grade: N42, Plating: Nickel, Performance (Gauss): 3600, Vertical Pull (Kg): 3.8".
    I am not sure how this information would help me in knowing whether the magnet can actually attract the mass of iron I have. Can someone explain this to me please?
