A single circular loop of wire with radius \( 0.020 \mathrm{~m} \) carries a current of \( 8.0 \mathrm{~A} \). It is placed at the center of a solenoid that has length \( 0.65 \mathrm{~m} \), radius \( 0.080 \mathrm{~m} \), and 1400 turns.
Solenoid
Current-carrying loop
Determine the value of the current in the solenoid so that the magnetic field at the center of the loop is zero tesla.
(A) \( 1.4 \times 10^{-1} \mathrm{~A} \)
(B) \( 4.4 \times 10^{-2} \mathrm{~A} \)
(C) \( 9.3 \times 10^{-2} \mathrm{~A} \)
(D) \( 2.5 \times 10^{-4} \mathrm{~A} \)
