A small circular loop of radius
l=1 cm is kept inside a larger circular loop of radius r such that both are coplanar and concentric. If the current in larger loop is as shown in the graph, then current induced in the smaller loop any time is represented as
In at any instant. Take anticlockwise current as positive. List -1 contains time instants, and List-2 contains the values for
In. Match them. Take
μ0π2Rr=1.
