    Force on a wire in a magnetic field.
    If a 190 cm wire carrying 15.00 A of current [up] experiences a force [north] of 0.60N,

    a)What is the direction and magnetic field intensity that is causing this?
    b)At what angle would the field need to be at to have the force experienced?

    a) use

    B is the magnetic field strength,
    I is the current,
    l is the length of the wire
    and F is of course the force.

    I'll ask you again to state the direction you think is correct and the reason why would you think so :)

    b) Same thing here, post and say why you think so first, then we'll look into it, though I think the question could be worded better.
