Question 1

An ideal solenoid of length 10 cm consists of a wire wrapped tightly around a wooden core. The magnetic field strength is inside the solenoid. If the solenoid is stretched to by applying a force to it, what does the magnetic field become?
◦ 20 T
◦ 10.0 T
◦ 1.6 T
◦ 4.0 T

Question 2

An ideal solenoid is wound with 470 turns on a wooden form that is 4.0 cm in diameter and 50 cm long. The windings carry a current in the sense shown in the figure. The current produces a magnetic field of magnitude at the center of the solenoid. What is the current I in the solenoid windings? (μ0 = 4π × 10-7 T ∙ m/A)



◦ 3.9 A
◦ 2.6 A
◦ 3.0 A
◦ 3.5 A
◦ 4.3 A
