Questions
Two loops with sides L and l (L>>l) are placed concentrically and coplanar as shown in fig. (9). The
mutual inductance of the system is proportional to
a
l2/L2
b
L2/l2
c
l/L2
d
l2/L
detailed solution
Correct option is D
The value of B is given byB=22μ0iπLThe flux linked with the smaller loopΦ=Mi=BA=Bl2∴Mi=22μ0il2−I or m∝l2/LTalk to our academic expert!
