Question 92 of 153

A constant magnetic field of $1T$ is applied in the $x\gt 0$ region. A metallic circular ring of radius $1m$ is moving with a constant velocity of $1m{s}^{-1}$ along the $x$-axis. At $t=0s$, the centre $O$ of the ring is at $x=-1m$. What will be the value of the induced emf in the ring at $t=1s$ ? (Assume the velocity of the ring does not change.)
