[单选题]
A bar magnet is aligned along the axis a0ld pds/ng 8/+lly5v of a conductinvtb9; ttm*561;du vew b,iiltg loop. The magnet and the loop move wituw d ti1;i b;*tebt9v,lmv6t5h velocities as given situations$K$,$L$, and $M$. The distance between the bar and loop is the same in all scenarios.


Which is correct about the magnitudes of induced emf, $\epsilon$, at the instant shown in each situation?

A. ${\epsilon }_K={\epsilon }_L>{\epsilon }_M$
B. ${\epsilon }_L>{\epsilon }_K={\epsilon }_M$​
C. ${\epsilon }_M>{\epsilon }_K>{\epsilon }_L$​
D. ${\epsilon }_K>{\epsilon }_L>{\epsilon }_M$
