1 of 11 A steady current I is flowing through a straight wire of finite length. Review Constants Part A Find B1, the magnitude of the magnetic field generated by this wire at a point P located a distance I from the center of the wire. Assume that at P the angle subtended from the midpoint of the wire to each end is 0. as shown in the diagram (Figure 1). Express your answer in terms of I, I, 0m, and k= Po/(4n). ► View Available Hint(s) B1 kI-2sin(8) Previous Answers All attempts used; correct answer displayed The magnetic field for an infinitely long wire can be obtained by setting 0 =T/2 in the previous expression. This gives a magnetic field 2kT B = which you probably derived in an earlier problem or in lecture using the Biot-Savart law. Figure K1 of 2 > Part B Now find B, the magnetic field generated by this wire at a point P located a distance I from either end of the wire. ASsume that at P the angle subtended from the end of the wire to the other end is Oend as shown in the diagram (Figure 2).
