A solenoid of radius r = 1.25 cm and length l = 33.0 cm has 320 turns and carries 12.0 A.
(a) Calculate the flux through the surface of a disk-shaped area of radius R = 5.00 cm that is positioned perpendicular to and centered on the axis of the solenoid as in the figure (a) above.
What is the magnitude of the magnetic field inside the solenoid?
