1. Inductance. Consider the configuration of a wire with 90° bends as shown below. A small loop,
with its sides of length a and width d = a/16 is placed with its plane lying along xz principal plane
as shown. Stating all assumptions, determine mutual inductance between the loop and the wire.

1. A cylindrical conductor wire is made using gold (o = 4.1 × 107 S/m) and silver (o =
6.3 × 107 S/m) as shown in the figure. 1 km section of the cylindrical conductor is made of gold and 2
km section of the cylindrical conductor is made of silver. The radius of the cylinder is r = 4 mm. A DC
current of 20 A is flowing through 3 km of this wire.
