That due to faraday's law, when faraday's law of electromagnetic induction, this states that an electric field is induced in any region of space in which a magnetic field is changing with respect to time.
00:27
So we know that in this case there is a part of earth's magnetic field enclosed in the loop of wire embedded in the road surface.
00:37
We can say that in this closed loop, a portion of earth's magnetic field lies.
01:00
And due to this, we can say that this enclosed magnetic field is momentarily altered whenever an automobile passes.
01:10
And this is due to iron present in the automobile.
01:19
So because of that iron present in the automobile due to some of its iron parts, this closed loop will have an electric field induced.
01:32
And so due to this, we can say that yes, we can say that earth's magnetic field will will be momentarily altered within the loop.
02:02
Now, the slight change in the magnetic field inside the loop of the wire on the road results in the generation of eddy currents.
02:13
So we can say that this slight change will produce eddy currents.
02:35
And due to this, we can say that we need.
02:39
That any current's flow enclosed loops within conductors in planes perpendicular to the magnetic field...
