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?
What is the peak emf generated by rotating a 1000-turn, 20.0 cm diameter coil in the Earth’s 5.00105T magnetic field, given the plane of the coil is originally perpendicular to the Earth’s field and is rotated to be parallel to the field in 10.0 ms?
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.
Make a drawing similar to Figure 23.14, but with the pendulum moving in the opposite direction. Then use Faraday’s law, Lenz’s law, and RHR—l to show that magnetic force opposes motion.
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?
Calculate the Hall voltage induced on a patient’s heart while being scanned by an MRI unit. Approximate the conducting pain on the heart wall by a wire 7.50 cm long that moves at 10.0 cm/s perpendicular to a 1.50T magnetic field.
Explain how magnetic flux can be zero when the magnetic field is not zero.
Unreasonable results To construct a non-mechanical water meter, a 0.500-T magnetic field is placed across the supply water pipe to a home and the Hall voltage is recorded, (a) Find the flow rate through a 3.00-cm-diameter pipe if the Hall voltage is 60.0 mV. (b) What would the Hail voltage be for the same flow rate through a 10,0-cm- diameter pipe with tire same field applied?
Suppose a 50-turn coil lies in the plane of the page in a uniform magnetic field that is directed into the page. The coil originally has an area of 0.250 m2. It is stretched to have no area in 0.100 s. What is the direction and magnitude of the induced emf if the uniform magnetic field has a strength of 1.50 T?
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?
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?
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?
