Q.A search coil having 2000 turns with area 1.5 cm$^2$ is placed in a magnetic field of 0.60 T. The coil is moved rapidly out of the field in a time of 0.2 second. Calculate the induced emf across the search coil.

[!TLDR] $e=\frac{NBA}{t}=\frac{(2000)(0.6)(1.5\times10^{-4})} …

The search coil has N=2000 turns, area $A=1.5\,\text{cm}^2=1.5\times10^{-4}\,\text{m}^2$, initially in a field B=0.60 T, moved completely out of the field in $t=0.2$ s (so the field at the coil falls from 0.60 T to 0). By the flux rule, $$|e|=N\left|\frac{\Delta\Phi}{\Delta t}\right|= …

Apply the flux rule for a coil moved out of a field: the flux falls from $NBA$ to zero ov …

Using the coil's area in $\text{cm}^2$ directly without converting to $\text{m}^2$, which would give …
