Chapter 21, Problem 3MCQ

The magnetic flux through a ${\text{10 0-cm}}^{\text{2}}$ loop is $\text{8}\text{.0 T }\cdot {\text{ cm}}^{\text{2}}$, and the magnetic field at the location of the loop is uniform. Choose all correct answers.

a. The magnitude of the $\stackrel{\to }{B}$ field must satisfy the condition $B\le 0.8\text{ T}.$

b. The direction of the $\stackrel{\to }{B}$ field cannot be perpendicular to the surface of the loop.

c. If the direction of $\stackrel{\to }{B}$ field is parallel to the normal to the loop's surface, then $B=0.8\text{ T}.$

d. If B = 1.0 T. then the angle between the $\stackrel{\to }{B}$ field and the normal to the loop's surface is greater than $0°$
