N1/N2 = L1/L2; where N is the number of turns and L is the inductance.

Inductance = (u N^2A)/lenth.
L1 =(u*10^2 A)/length =(u* 100A)/lenght = 5 micro henery.
L2 =u*20^2A)/2*length = 2 ((u* 100A)/lenght) = 10 micro henry.
L1 =(u*10^2 A)/length =(u* 100A)/lenght = 5 micro henery.
L2 =u*20^2A)/2*length = 2 ((u* 100A)/lenght) = 10 micro henry.
