When you move a magnet through a 1 loop coil you detect a voltage of 0.001 volts, what voltage would you read if you move the same magnet at the same velocity through a coil with 1000 loops (assume the radius of the loops in the coil is the same as the one in the single loop wire) 1x10^-6 volts 1x10^-3 volts 1 volt 1000 volts

What are the directions of the currents in the loop and coils shown in Figure 22.61?
A spacecraft orbiting the Earth has a coil of wire in it. An astronaut measures a small current in the coil, although there is no battery connected to it and there are no magnets in the spacecraft. What is causing the current?
The source of a generator’s electrical energy output is the work done to turn its coils. How is the work needed to turn the generator related to Lenz's law?
Why would a magnetohydrodynamic drive work better in ocean water than in fresh water? Also, why would superconducting magnets be desirable?
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?
We often assume that the magnetic field is uniform in a legion and zero everywhere else. Show that in reality' it is impossible for a magnetic field to drop abruptly to zero, as illustrated in the accompanying figure. (Hint; Apply Ampere's law over the path shown.)
Suppose you find that the belt drive connecting a powerful motor to an air conditioning unit is broken and the motel is running freely. Should you be worried that the motor is consuming a great deal at energy for no useful purpose? Explain why or why not.
Figure 22.57 shows a long straight wire near a rectangular current loop. What is the direction and magnitude of the total force on the loop?
A strong electromagnet produces a uniform magnetic field of 1.60 T over a cross-sectional area of 0.200 m2. A coil having 200 turns and a total resistance of 20.0 is placed around the electromagnet. The current in the electromagnet is then smoothly reduced until it reaches zero in 20.0 ms. What is the current induced in the coil?
The 12.0 cm long rod in Figure 23.11 moves at 4.00 m/s. What is the strength of the magnetic field if a 95.0 V emf is induced?
Measurements affect the system being measured, such as the current loop in Figure 22.56. (a) Estimate file field the loop creates by calculating the field at the center of a circular loop 20.0 cm in diameter carrying 5.00 A. (b) What is the smallest field strength this loop can be used to measure, if its field must alter the measured field by less than 0.0100%?
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?
