Please explain your answer. Problem 1: 20 Points A loop of wire has a 90 bend in it, creating two sermicircles of current with point P as the center point for both semicirles. Both semicircles have a radius a and the same current I is flowing through the whole sysI tem a) Define a Coordinate System, then define and 1๕สึ for one semicircle of the wire if the point we care about is at point P using the magnetic fleld of a tiny slice of wire (Biot-Savart) P.
