Indicate whether the magnetic field created in each of the three situations shown in Figure 22.59 is into or out of the page on the left and right of the current.
If one of the loops in Figure 22.49 is titled slightly relative to the other and then currents are in the same direction, what are the directions of the torques they exert on each other? Does this imply that the poles of the bar magnet—like fields they create will line up with each other if the loops are allowed to rotate?
Use Faraday’s law, Lenz’s law, and RHR—l to show that the magnetic force on the current in the moving rod in Figure 23.11 is in the opposite direction of its velocity.
A patient with a pacemaker is mistakenly being scanned for an MRI image. A 10. 0-cm-long section of pacemaker wire moves at a speed of 10.0 cm/s perpendicular to the MRI unit’s magnetic field and a 20.0-mV Hall voltage is induced. What is the magnetic field strength?
While operating, a high-precision TV monitor is placed on its side during maintenance. The image on the monitor changes color and blurs slightly. Discuss the possible relation of these effects to the Earth’s magnetic field.
List the ways in which magnetic field lines and electric field lines the similar. For example, the field direction is tangent to the line at any point in space. Also list the ways in which they differ. For example, electric force is parallel to electric field lines, whereas magnetic force on moving charges is perpendicular to magnetic field lines.
Noting that the magnetic field lines of a bar magnet resemble the electric field lines of a pair of equal and opposite charges, do you expect the magnetic field to rapidly decrease in strength with distance from the magnet? Is this consistent with your experience with magnets?
Explain how magnetic flux can be zero when the magnetic field is not zero.
What is the value of the magnetic flux through the coil in Figure 23.56 (b) due to the wire?
Integrated Concepts A lightning bolt produces a rapidly varying magnetic field. It the belt strikes the earth vertically and acts like a current in a long straight wire, it will induce a voltage in a loop aligned like that in Figure 23.57 (b). What voltage is induced in a 1.00 m diameter loop 50.0 m from a 2.00106A lightning strike, if the current falls to zero in 25.0s ? (b) Discuss circumstances under which such a voltage would produce noticeable consequences.
If a current flows in the Satellite Tether shown in Figure 23.12, use Faraday’s law, Lenz'S law, and RHRl to show that there is a magnetic force on the rather in the direction opposite to its velocity.
Integrated Concepts A pendulum is set up so that its bob (a thin copper disk) swings between the poles of a permanent magnet as shown in Figure 22.63. What is the magnitude and direction of the magnetic force on the bub at the lowest point in its path, if it has a positive 0.250C charge and is released from a height of 30.0 cm above its lowest point? The magnetic field strength is 1.50 T. (b) What is the acceleration of the bob at the bottom of its swing it its mass is 30.0 grams and it is hung from a fiexible string? Be certain to include a free-body diagram as pan of your analysis.
