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 mWb
b. 16 mWb
c. 0.25 mWb
d. 10 mWb
e. 5.0 mWb

Question 2

A segment of wire of total length 2.0 m is formed into a circular loop having 5.0 turns. If the wire carries a 1.2-A current, determine the magnitude of the magnetic field at the center of the loop.
a. 79 mT
b. 69 mT
c. 59 mT
d. 89 mT
e. 9.4 mT
