Alternating current can induce voltage because it has a
-
A.
ripple value -
B.
varying magnetic field -
C.
weaker magnetic field than direct current -
D.
stonger magnetic field than direct current -
E.
high peak value
Correct Answer: Option B
Explanation
Due to the change in the voltage in an AC, which either increases or decreases, the magnetic field around it is alwats eithercollapsing or expanding (varying magnetic field).
