Homework: Magnetic Induction Excursions Name Magnetically induced emf depends the time rate of change of magnetic flux. The magnetic flux through a wire loop depends on what two factors? rec 2. Mogne lie field strorgh A copper hoop is held in a horizontal plane in a uniform magnetic field whose field lines run along the east-west direction, as shown in the figure (viewed from above). The hoop is moved in the following ways. In terms of magnetic induction and the factors listed in 1 and 2 above, explain how each will or will not result in an induced emf 3. rotated about a north-south axis 4. rotated about an east-west axis 5. moved rapidly, without rotation, toward the west 6. moved rapidly, without rotation, toward the south 7. moved rapidly, without rotation, out of the page 8. Describe one other way to produce an induced emf in the hoop.Explanation / Answer
3. will induce emf since the angle for the magnetic flux will change as it is rotated about the north-south axis
4. will not induce emf since the flux will not change
5.
will not induce, since the hoop moves parallel to magnetic field lines.
6.
will induce emf , since the area inside the magnetic field for the hoop will change
7.
