3 Biot-Savart for Curved Wire
A segment of a closed current loop is shown in the following figure.
Compute the magnetic field at the center of the semi-circle due to the
straight and curved segments shown.

(Technically, to use the Biot-Savart law for currents in a wire, the current
must be constant, and the wire must form a closed loop. As a result, there
will be a contribution to the magnetic field at the origin due to the parts of
the closed loop that are not shown. However, here we assume that the not-
shown part of the loop is far enough away that they can be neglected.)
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.

- Two long, parallel wires are 6 m apart. They carry steady currents of 10 A each, in opposite directions. Place a third long wire in parallel with the two wires, at a distance of 5 m from each of the two wires.
