What is the direction of the velocity of a negative charge that experiences the magnetic force shown in each of the three cases in Figure 22.51, assuming it moves perpendicular to B?
Inside a motor, 30.0 A passes through a 250-turn circular loop that is 10.0 cm in radius. What i5 the magnetic field strength created at its center?
What is the direction of the magnetic force on a positive charge that moves as shown in each of the six cases shown in Figure 22.59?
When a magnet is thrust into a coil as in Figure 23.4(a), what is the direction of the louse exerted by the coil on the magnet? Draw a diagram showing the direction of the current induced in the coil and the magnetic field it produces, to justify your response. How does the magnitude of the force depend on the resistance of the galvanometer?
Explain why the magnetic field would not be unique (that is, not have a single value) at a point in space where magnetic field lines might cross. (Consider the direction of the field at such a point.)
(a) A 0.750-m-long section of cable carrying current to a car starter motor makes an angle of GOP with Earth's 5.5105T field. What is the current when tire wire experiences a farce of 7.010N? (b) If you run the wire between the poles of a strong horseshoe magnet, subjecting 5.00 cm of it to a 1.75-T field, what force is exerted on this segment of wire?
Explain how magnetic flux can be zero when the magnetic field is not zero.
Consider a magnetic field that is uniform in direction throughout a certain volume. (a) Can the field be uniform in magnitude? (b) Must it be uniform in magnitude? Give evidence for your answers.
What force is exerted on the water in an MHD drive utilizing a 25.0-cm-diameter tube, it 100-A current is passed across the tube that is perpendicular to a 2.00T magnetic field? (The relatively small size of this force indicates the need for very large currents and magnetic fields to make practical MHD drives.)
A particle’s path is bent when it passes through a region of non-zero magnetic field although its speed remains unchanged. This is very useful for “beam steering’’ in particle accelerators. Consider a proton of speed 4106m/s entering a region of uniform magnetic field 0.2 T over a 5-cm-wide region. Magnetic field is perpendicular to the velocity of the particle. By how much angle will the path of the proton be bent? (Hint: the particle comes out tangent to a circle.
The rod shown in the accompanying figure is moving through a uniform magnetic field of strength B=0.50T with a constant velocity of magnitude v=8.0m/s . What is the potential difference between the ends of the rod? Which end of the rod is at a higher potential? B
