The figure below shows an infinitely long current filament wound in the form of a circular helix with radius R and pitch l , i.e., is the distance along the z-axis occupied by one wind of the helix. Find the ρ dependence of the magnetic field B(ρ,φ, z) in the limit ρ. Does the → 0 limit make sense?
