A rectangular wire loop of sides 8 cm and 2 cm with a small cut is moving out of a region of uniform magnetic field of magnitude 0.3 T directed normal to the loop. What is the mef developed across the cut if the velocity of the loop is 1 m. `s^(-1)` in a direction normal to the
shorter side of the loop? For how long does the induced voltage last in each case?

Explanation

`e=Bl'v=0.3xx2xx10^(-2)xx10^(-2)=0.6xx10^(-4)V`
`therefore` Time, `t_(2)=(l)/(v)=(8)/(1)=8s`
