Question:

The flux through the solenoid of Problem 32.17 is reduced to a value of 1.0 mWb in a time of 0.050 s. Find the induced emf in the solenoid.


Problem 32.17

Figure 32-9(a) depicts a two-turn horizontal coil in a uniform downward b-field. Assume the field is decreasing. 

What is the direction of the induced magnetic field in the coil and why? 

What is the direction of the induced current in the coil and why? 

Which terminal is at a higher voltage?X X X x A (a)  * X B x B x X
