question 31

Multiple Choice

The figure shows the cross-section of a hollow cylinder of inner radius a = 5.0 cm and outer radius b = 7.0 cm. A uniform current density of 1.0 A/ cm² flows through the cylinder parallel to its axis. Calculate the magnitude of the magnetic field at a distance of d = 10 cm from the axis of the cylinder.

• A) 0.00 T
• B) 1.5 × 10^-4 T
• C) 2.5 × 10^-4 T
• D) 4.5 × 10^-4 T
• E) 0.50 × 10^-4 T
