Homework Help: Rectangular coil in a galvanometer

  1. May 23, 2005 #1
    Good day everyone, I was wondering how would you determine the magnetic field within a square coil? My colleague and I are trying to write a lab up on tangent galvanometers, but all we can find are models with circular coils, and ours is square. Any help is appreciated.

    Are you trying to find the magnetic field produced by the coil, or are you trying to find the torque on the coil because it is carrying a current in a magnetic field? The latter is the usual problem one has to deal with when talking about meters, and it is easier to do for a square than for a circle. The field produced by a square coil at all points in the vacinity of the coil is not a trivial task, and I suspect that is not what you are being asked to do.
