Homework Help: Calculating horizontal force from disc magnet

  1. Jan 3, 2012 #1
    1. The problem statement, all variables and given/known data
    I want a box shaped robot to move on the ceiling. The robot sticks to the ceiling using magnets. I am attaching a picture. The red is a magnet. How do I calculate how much force is needed to move the robot horizontally? I know very little physics and I need to figure out how strong my motors need to be.

    2. Relevant equations
    This is the kind of magnet i will be using

    3. The attempt at a solution
    This is not actually a homework problem. Its for a robotics project.
