A circular loop with radius R is in a magnetic field that is perpendicular to it. Assume that the normal to the loop is in the same direction as the field. The strength of the field, as a function of radial distance from the center r, is given by B=kr (where k is a constant). What is the flux over the loop? My plan for this problem was to take the integral of the function of the magnetic field B=kr....
