154661 Two coils $P$ and $Q$ are kept near each other. When no current flows through coil $P$ and current increases in coil $Q$ at the rate $10 \mathrm{~A} / \mathrm{s}$, the e.m.f. in coil $P$ is $15 \mathrm{mV}$. When coil $Q$ carries no current and 1.8 A current flows through coil $P$, the magnetic flux linked with coil $Q$ is

154662 Three identical coils $X, Y$ and $Z$ are placed with their planes parallel to each other. Coils $X$ and $Z$ carry current as shown in the figure. Coils $X$ and $Y$ are fixed and coil $Z$ is moved towards $Y$, then
