Question

An infinitely long conductor carrying current is bent at a right angle as shown in Figure 1. Point Pis located a distance b from the corner of the wire. Only one section of this current contributes to the magnetic field at pt. P. Why? The general formula (derived from the Biot-Savart Law) for the magnitude of the magnetic field a distance a away from a thin, straight conductor is: B = f (sin 8, - sin 02) For this problem, what are the values for the following variables: 0,- 8, the value should be negative. why?) (1.) 0.75 point ifb1.00 cm and I 6.00 A, what is the magnitude of the magnetic field at point P, in T (micro-Tesla)? (2.) 10.25 pointWhat is the direction of the magnetic field at point P7 (ted direction using the left-hand rule Another very, very long conductor is located a distance 2b to the right of point P (as shown in Figure 2). and carries a current of 3 toward the top of the page, as shown. e top of Figure 2 (3.) 10.5 point] What is the direction of the magnetic field due to just the second, straight current at point P? 31 (4.) [1 point] What is the net magnitude of the magnetic field at point P due to both current-carrying conductors, indt? (5.) 0.5 point What is the direction of the net magnetic field (due to both current-carrying conductors) at point ?
