A rectangular coil having 200 turns and size `0.30 xx 0.05 m^2` is placed perpendicular to a magnetic field. The field changes from `5x10^(-3)` `Wbm^(-2)`to `2x10(-3)` `Wbm(-2)` in the time interval of 3 millisecond. Calculate the e.m.f. induced in the coil. If the resistance of the coil is `15Omega`, find the value of current flowing through it.
