    Analyze all forces (electrical and magnetic) acting upon the coil in the following picture. List all the variables needed and give the formula for calculating each force.

    Note that this is a 3D cylindrical coil.

    There might be different possible situations. Discuss them all.

    Since we don't do people's homework for them, please describe what you've done so far. How have you approached the problem (other than saying "do my work for me")? How are you thinking about solving it? Where did you get stuck? What have you tried in order to get unstuck?

    We're happy to help you learn.

    Okay I might have phrased this in a way that sounds like a homework problem but it's not. I'm just curious about how everything actually works in here.

    For the most obvious, the coil has N pole to the left and S to the right which basically means it will get a magnetic force from the S on the left attracting it and the S on the right repelling it.

    Then there's electricity current in a magnetic field caused by the two S poles. So if we look at a cross-section of the coil we would see something like this (from right to left):

    For each point on a loop of the coil there's a electromagnetic force to the left.

    Apart from these forces I'm not sure of any others. I want to know exactly how every force is going to act.
