Questions
A small square loop of wire of side l is placed inside a large square loop of wire of side The loops are coplanar and their centre coincide. The mutual inductance of the system is proportional to
detailed solution
Correct option is B
Magnetic field produced due to large loop,B=μ04π82iLFlux linked with smaller loop,ϕ=B(l)2=μ04π82il2L∴ϕ=Mi⇒M=ϕi=μ04π⋅82l2L⇒M∝l2LTalk to our academic expert!
