Homework Help: Mutual inductance in air

  1. Jul 15, 2007 #1
    1. The problem statement, all variables and given/known data

    Find the mutual inductance in air between a long straight filament and a coplanar square loop, 10cm on a side, with its nearest edge parallel to and 10cm from the filament.

    2. Relevant equations

    What equations should be best in solving this problem?

    3. The attempt at a solution

    I used M = N (Phi) / I, found B (flux density) and then found the magnetic total flux Phi, and I got the answer of
    13.86 nH, but it seems that this way is a bit convoluted, if it is right.

    Thanks for any help
