Answer:

0.50v

Explanation:

Now EMF is induced when there is motion of a conductor in an electric field. Michael Faraday in the annals of scientific history discovered this.

This is expressed mathematically as;

E = Magnetic field / t

but t = d/ v; d- distance, v-velocity, time

Hence E = magnetic field/ d/v

= Magnetic field× v/ d

= 0.02×30/ 1.2= 0.5
