Two Parallel Conductors Are Carrying Currents in the Same Direction $\mu$

question 51

Multiple Choice

Two parallel conductors are carrying currents in the same direction. The currents are non-zero and not necessarily equal. The magnitude of the magnetic field midway between them is 40 $\mu$ T. If one of the currents then has its direction reversed, what is the resulting magnitude of the magnetic field midway between them?

• A) It could be any value.
• B) 40\(\mu\)T
• C) a value less than 40 \(\mu\)T
• D) a value greater than 40 \(\mu\)T
