The magnetic flux penetrating the conductor circuit changed by 4 mWb in 0.2 s. What is the rate of change in magnetic flux? What is the EMF of induction in the circuit?
EMF = rate of change of magnetic flux.
E = delta F / delta t
Given: delta Ф = 4 mVb = 0.004 Wb, delta t = 0.2 s
Find: E
Decision:
E = 0.004 Wb / 0.2 s = 0.02 Wb / s
Answer: E = 0.02 Wb / s.
