Te current density in a cylindrical conductor of radius r

Reference no: EM13620639

The current density in a cylindrical conductor of radius R = 44.9 cm, varies as J(r) = J0r/R (in the region from zero to R), where J0 = 0.449 C/m2. a) Find the magnitude of the magnetic field at r = 22.45 cm. b) Find the magnitude of the magnetic field at r = 89.8 cm.
