  A) 3.4 N
  B) 1.6 N
  C) 2.2 N
  D) 3.2 N
  E) 1.2 N

Question 2

Explain what happens when the angular speed of the coil in an electric generator is increased.
 
  What will be an ideal response?

Answer to Question 1

B

Answer to Question 2

When the angular speed of the coil in an electric generator is increased, the rate at which the magnetic flux changes increases as well. As a result, the magnitude of the induced emf produced by the generator increases. Of course, the frequency of the induced emf increases as well.
