$A$ moving conductor coil in a magnetic field produces an induced $e.m.f$. This is in accordance with

$A$ metallic loop is placed in a uniform magnetic field $B$ with the plane of the loop perpendicular to $B$. Under which condition will an electromotive force (emf) be induced in the loop? "If the loop is ....."

There are two square loops $A$ and $B$. When $A$ moves towards $B$,a current starts flowing in $B$ as shown in the figure,and the current in $B$ stops when $A$ stops moving. From this,we can infer that (Assume loop $B$ is at rest):

In the following figure, the magnet is moved towards the coil with a speed $v$ and the induced emf is $e$. If the magnet and the coil recede away from one another, each moving with a speed $v$, the induced emf in the coil will be

$A$ coil has an area of $0.05\,m^2$ and it has $800\,turns$. It is placed perpendicularly in a magnetic field of strength $4 \times 10^{-5}\,Wb/m^2$. It is rotated through $90^o$ in $0.1\,s$. The average emf induced in the coil is ........... $V.$

$A$ magnetic field of $2 \times 10^{-2} \, T$ acts at right angles to a coil of area $100 \, cm^2$ with $50$ turns. The average emf induced in the coil is $0.1 \, V$,when it is removed from the field in time $t$. The value of $t$ is $... \, sec$.
