Suppose a magnet is moved back and forth through two different coils at a constant frequency. Coil A measures a higher EMF than Coil B. Which coil has more loops and why? a) Coil A has more loops because decreasing length will increase EMF. b) Coil B has more loops because decreasing length will increase EMF. c) Coil A has more loops because increasing length will increase EMF. d) Coil B has more loops because increasing length will increase EMF
