Homework Help: Magnetic field and gradient along axis of antihelmholtz pair

  1. Mar 16, 2016 #1
    1. The problem statement, all variables and given/known data
    An anti-Helmholtz pair consists of two circular coaxial current loops each with radius R and spaced a distance R apart from each other. The loops carry current I in opposite directions.
    1) Calculate the magnetic field and the magnetic field gradient along the axis at the center.
    2) Calculate the 1st order deviation from the value of the gradient calculated in (1) for small displacements from the center of the pair along the axis.

    2. Relevant equations

    3. The attempt at a solution
    Is it not just zero?
