An infinite (filled) cylinder of radius a = 0.3 cm is carrying current with a current density given by: T j= jo- where jo = 2.7 × 107 A/m² In the center of the cylinder passes a long, thin, infinite wire (in blue) which carries all the current passing through the cylinder back in the other direction. Z I a. What is the size of the magnetic field at r = 0.1 cm? 1.56 b. What is the magnetic field at r = 0 0.9 cm?
