Apair of adjacent coils has a mutual inductance of 1.5 H. If the current in one coil changes from 0 to 20 A in 0.5 s, what is the change of flux linkage with the other coil?

Accepted Answer

$  E= - M\:  \frac{\mathrm{d} i }{\mathrm{d} t}=\, \frac{\mathrm{d} \phi }{\mathrm{d} t}$ $	herefore\,\,  d\phi\,=\,M. \,di$ $ \,  d\phi\,=\,1.5(20-0) \, $ $ \,  d\phi\,=\, 30 \, wb$
