A 1.2 m steel rod moves through a uniform magnetic field of 0.020 T at 30 m/s. What emfis induced between the two ends of the steel rod?

0.36 V

0.50 V

0.60 V

0.72 V

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

0.50 V

Explanation: yea that's the answer
