Question

JI,) a steady current density J = Ê Jer,p) OCR-), where Ol B-r) is the Heaviside O-function, flows in a cylindrical wire of radius R with a central axis along the z-axis of coordinates, set up the piot-Savart integral for the magnetic field Br. 63) at a general field point P. Your integral should have sto vector symbols Cepoept for rectangular unit vectors
