A conductor suspended by two flexible wires as shown in the figure below has a mass per unit length of 0.0396 kg/m. A rectangular loop forms a circuit, and is suspended from a horizontal surface by two wires that attach to the top right and left corners of the loop. The bottom of the loop is immersed in a magnetic field vector Bin, which points into the page. The top of the loop contains a power source, the positive terminal...

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,...

Wednesday Homework Problem 9.7 The figure to the right shows a square coil of wire in the plane of the page and a constant magnetic field pointing out of the page. The coil rotates in the direction drawn. The coil develops an angular velocity of 250Hz about its axis. For this problem assume 0o 0. The earth's magnetic field strength is still about 2.3 x 10-2T. The sides of the square coil are 6cm long. The coil has one turn...
