12 Figure 32-26 shows foursteel bars; three are perma-nent magnets. One of the polesis indicated. Through experi-ment we find that ends a and dattract each other, ends c and frepel, ends e and h attract, andends a and h attract. (a) Whichends are north poles? (b)Which bar is not a magnet?Figure 32-26 Question 12.

a) End a and end e attracts to each other. Hence end e must be South Pole. The other end which is…

Figure 28-29 shows a rectangular 28-turn coil of wire, of dimensions 10 cm by 5.0 cm. It carries a current of 0.80 A and is hinged along one long side. It is mounted in the XY plane, at angle θ=25∘θ=25∘ to the direction of a uniform magnetic field of magnitude 0.50 T. In unit vector notation, what is the torque acting on the coil about the hinge line? Please show step by step in solving this problem. Thanks

A long straight very thin wire on the y-axis carries a 10-A current in the positive y-direction. Acircular loop 0.50 m in radius, also of very thin wire and lying in the yz-plane, carries a 9.0-Acurrent, as shown. Point P is on the positive x-axis, at a distance of 0.50 m from the center of theloop. What is the magnetic field vector at point P due to these two currents?
