Main Question or Discussion Point

hi,
in this problem here

The effect of inductor A on inductor B is to induce a emf in B and is due to the time rate of change of the current that is flowing in A and the mutual inductance..
i.e. emfB = - MABdIa/dt

Apparently the schematic diagram does not represent the physical layout of the inductors. It's misleading in that respect.
