The six conductors as shown carry currents \( I_{1}= \) \( 1 \mathrm{~A}, \mathrm{I}_{2}=2 \mathrm{~A}, \mathrm{I}_{3}=3 \mathrm{~A}, \mathrm{I}_{4}=4 \mathrm{~A}, \mathrm{I}_{5}=5 \mathrm{~A} \) and \( \mathrm{I}_{6}=6 \mathrm{~A} \) into or out of the page. What is the value of the integral for loop (C)?
Select one:
a. \( \oint \overline{\mathrm{B}} \cdot \mathrm{d} \bar{l}=2 \mu_{0} \) (T.m).
(C)
b. \( \quad \oint \overrightarrow{\mathrm{B}} \cdot d \overline{\mathrm{C}}=3 \mu_{0}(\mathrm{~T} \cdot \mathrm{~m}) \).
(C)
c. \( \oint \overrightarrow{\mathrm{B}} \cdot \mathrm{d} \bar{\ell}=-3 \mu_{0}(\mathrm{~T} \cdot \mathrm{~m}) \).
(C)
d. \( \oint \overrightarrow{\mathrm{B}} \cdot \overline{\mathrm{C}} \bar{\epsilon}=-2 \mu_{0}(\mathrm{~T} \cdot \mathrm{~m}) \)
(C)
