If a wire or coil with an open circuit is moved through a magnetic field . O nothing will happen O a current will be generated through the coil O it depends on the speed O an EMF will be generated in or across the coil

There is 50 mA of current through a coil with 250 turns. The flux is 150 µWb. What is the mmf? What is the reluctance of the circuit?     A. Fm = 1.25 At   -   R=4.3x10-3 At/Wb   B. Fm = 2.25 At   -   R=8.3x10-3 At/Wb   C. Fm = 1.25 At   -   R=8.3x10-3 At/Wb   D. Fm = 1.25 At   -   R=8.3x10-2 At/Wb
