AGENDA




1 of 3

Closed loops A and B are drawn in the vicinity of a long straight current carrying wire. Loop A lies in a plane perpendicular to the wire, while B lies in a plane that is nearly parallel with the wire. The path integral of the magnetic field for B is

1. Greater than that for A.2. Equal to that for A.3. Less than that for A.

A

B

I




2 of 3Imagine two line currents flowing perpendicular to the display, equal in magnitude but opposite in direction. Consider the two loops shown, a and b. Which is true about the path integral of B around the two loops?

1. It is zero for both.2. It is the same for both, but not zero.3. It is zero for a but not for b.4. It is zero for b but not for a.

II

a

b




3 of 3

A solenoid is driven by 60 Hz AC. This means that the magnetic field changes direction inside the solenoid 60 times a second. An iron (ferromagnetic) rod

1. Will feel an attraction to the solenoid.2. Will feel a repulsion by the solenoid.3. Will have no average force applied to it.
