Multiple Choice
A solenoid 4.0 cm in radius and 4.0 m in length has 8 000 uniformly spaced turns and carries a current of 5.0 A. Consider a plane circular surface (radius = 2.0 cm) located at the center of the solenoid with its axis coincident with the axis of the solenoid. What is the magnetic flux through this surface? (1 Wb = 1 T ⋅ m2)
A) 63 μWb
B) 16 μWb
C) 0.25 mWb
D) 10 μWb
E) 5.0 μWb
