    field direction and magntiude

    could you polease expand on the formula. what numbers do i plug in for mg?

    m - mass of the wire
    g - 9.81N/Kg. The force which a 1Kg mass exerts due to gravity.

    The important thing isn't knowing which numbers to plug in where, it's understanding the principles behind the equation and where the equation comes from. Do you understand where the equation comes from?
