orthogonal to both v and B in the right-hand sense, as shown in Fig. 1.1b. The magnitude of the force is qvB sin , where  is the angle between v and B. Since the force is normal to v, there is no acceleration along the direction of motion. Thus the magnetic field changes only the direction of motion of the charge and does not alter the kinetic energy associated with it. Since current flow in a wire results from motion of charges in the wire, a wire of current placed in a magnetic field…

ever played with magnets you know about the fundamental law of all magnets: Opposites attract and likes repel. So if you have two bar magnets with their ends marked "north" and "south," then the north end of one magnet will attract the south end of the other. On the other hand, the north end of one magnet will repel the north end of the other (and similarly, south will repel south). Inside an electric motor, these attracting and repelling forces create rotational motion. In the above…

the Problem Let P represent the population of the United States, r the rate of consumption and N the number of aluminum cans used annually. The population of the United States is roughly 3×108 people. Let’s assume that, on average, each person drinks one can of soft drink every day. The mass of a soft-drink can is approximately 1.8 ×10−2 kg. (a) Express the number of cans N used annually in terms of the daily rate of consumption of soft drinks r and the population P: Substitute numerical…
