A Single Circular Loop of Wire with Radius 0

question 44

Multiple Choice

A single circular loop of wire with radius 0.025 m carries a current of 6.0 A. It is placed at the center of a solenoid that has length 0.60 m, radius 0.075 m, and 1200 turns.
-Determine the magnitude of the total magnetic field at the center of the loop (due both to the loop and the solenoid) if the current in the loop is reversed in direction from that needed to make the total field equal to zero tesla.

• A)2.5 × 10^-4 T
• B)3.0 × 10^-4 T
• C)4.4 × 10^-4 T
• D)6.7 × 10^-4 T
• E)8.2 × 10^-4 T
