Figure (a) shown two circular rings of radii a and b (a>b) joined together with wires of negligible resistance. Figure 3.15(b) shown thew pattern obtained by folding the small loop in the plane of the large loop. The pattern shown in Fig.3.15( c ) is obtained by twisting the small loop of Fig.3.15(a) through 180∘.
