A long straight wire carrying a current i=10 Ai=10 \mathrm{~A} and a rectangular metallic loop of dimensions b×c\mathrm{b} \times \mathrm{c} lie in the same plane as shown in the figure. The parameters are a=10 cm,b=30 cma=10 \mathrm{~cm}, b=30 \mathrm{~cm} and c=50 cmc=50 \mathrm{~cm}. The mutual inductance of the system is nearly A long straight wire carrying a current i=10 ~A and a rectangular metallic loop of dimensions b × c lie in the same
