20.71. Set Up: The Biot and Savart law is The wire and the vector from each short segment to point P are shown in Figure 20.71. For segment A, and For segment C, and Figure 20.71 Solve: (a) The right-hand rule says that is directed out of the page. (b) The right-hand rule says that is directed out of the page. Reflect: Both segments produce magnetic field at P that is in the same direction. At P the field due to segment C is larger than that due to segment A. 20.72. Set Up: The Biot and Savart law is The wire and the vector from the short segment to point P are shown in Figure 20.72. and Figure 20.72 Solve: The right-hand rule says that is directed into the page. 20.73. Set Up: The Biot and Savart law is The wire and the vector from the short segment to point P are shown in Figure 20.73. and Figure 20.73 Solve: The right-hand rule says that is directed into the page. Reflect: The current in the long straight segments also produces magnetic field at point
