Question 12, 13, 14, 15

The simple design with a slidable wire section can be treated as a generator. If the magnetic field is 0.65 T and the speed of the slide wire is 4.5 m/sec (L = 75 cm):

[Diagram Explanation]
The diagram illustrates a rectangular loop with a slidable wire segment. The segment ab, of length 75 cm, can move to the left with a speed of 4.5 m/s. The area abcd is subjected to a perpendicular magnetic field of 0.65 T. A resistor of 32Ω is connected to the loop at point d.

Questions:

12. Find the magnitude of the Emf.
   - a. 1.17 V
   - b. 2.19 V
   - c. 2.93 V
   - d. none

13. Find the current generated.
   - a. 36.6 mA
   - b. 91.6 mA
   - c. 68.4 mA
   - d. 28.4 mA

14. If the bar is treated like a battery (or a generator), in which direction will the current flow?
   - a. clockwise
   - b. counterclockwise
   - c. No current, only the emf voltage

15. Find the magnetic flux passing through area abcd, in Tesla·m² or Weber.
   - a. 48.8 Weber
   - b. 26 Weber
   - c. 1950 Weber
   - d. 0.195 Weber
