Question

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

Answer 1

0.50 V


Explanation: yea that’s the answer

Answer 2

0.50v

Step-by-step 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
