Assignment:
Consider this wire:
Each side is of length d and the point P¸ is even with the bottom horizontal wires and in the middle of the square area.
(a) Use the Biot-Savart law for currents to analyze the contributions of segments 1 and 5 to the magnetic field at point P.
(b) Compare the contributions of segments 2 and 4 to the magnetic field at point P (both magnitude and direction).
(c) The magnetic field at P is a sum of integrals, each one for a single segment of the wire. Write expressions for all the integrals needed to evaluate the magnetic field at P but do not try to do the integrals. You may draw on the example in your textbook to help you set the integrals up.
