Question 2 1 pts The figure below shows a cross-section of a solid cylinder, of radius Ta - 4.0 cm. The uniform current density inside the cylinder is J - 3.0 A/cm2. The current flows parallel to the axis of the cylinder. What is the magnitude of the magnetic field a distance rb - 2.0 cm away from the center of the cylinder? 8.8 x 10 'T 0 5.1 x 10-3T O 2.9 x 10 5 T O 7.0 x 10-4T O 3.8 x 10-4T
