And this from him. We have a circular region. Off areas are equal to three centimeters in which electric flux is actually going out off the page. So let us draw a circular region. This is a circular region. It has a radius, are there is an electric field which is deserting in a net electric flux. So I'll write as five e in in this case reversed. Oh, the electric field. So this man and this flux is due to the electric field. And as we said that this is actually waiting. So the radiation off electric flux through this office is killing as 0.6 world meet up a second or in six volt meter toe a second and it's dependent on the radial vector are so this is again multiply twit are who are the capital of capitalist over a radius on bearing with time T. Now, as for the problem, we need to find out the magnitude off induced magnetic field at radial distance two centimeters and five centimeters. First we'll write down that our is equal to three centimeters, so we need to find out the magnitude off induced magnetically to the first case is when our is less than our so are is equal to two centimeters. We'll use a formula that the girl closed loop, Peter, the l is the line element representing for the loop. It's equal to mu note I includes. This is the current which is enclosed within the loop. Now, as you can see, there is no current as such within the loop. In this case, however, there is also another part which is called the displacement current and rewrite that last minute I the displacement No idea is actually represented as since this part goes to zero. We write this a zero. This is, um, you know, absolutely not. Partial derivative off electric flux. Well, our name and that's a bit Oh dear. No considering so Vinto first consider our is equal to this. We have one small loop which is insane at a radius off are equal to present images are taking the fact that the magnetic flux in this case it's constant along the water loop with a be outside they get the magnitude off key into steel along the clothes look close group of circular so in particular is to buy our the artist that tedious. This gives us mu notes. Keeps little Lord the elevated off. This with respect to time he cancels out. So did we. Do not started canceling 30 course of a because of the radio, Uh, with calculus. So, as you can see, are now gets cancelled out. So the value off be that we are plain in this case, Yes. So the value of B that we often in this case, it's plain simple mathematics 10 and that men do is now equal to three point food into 10 pervert minus 17 Tesla. So this can be done by substituting for all the other values. Art gets cancelled out. We get a group, I 0.6. You have to substitute the values of these constant and are equal to three. Sentiment doesn't reflect this value for people next to move with the other section. This is friend. Are is equal to five centimeters. Now heavy. You'll have an interesting part. This is when our is actually greater than the capital are. It's which you can draw that neatly again. We go back to the same form, lovey. Right? B Dubai are this time our is after efi centimeters It is outside. The slim pickle surfaced. You not hopes, Eleanor. 16 However, we'll have to. Now consider vote are toe shoes. No. What are should be to lose him now. This represents this valley right here. This term actually represent the displacement, current and displacement current is purely due to the change in the electric field flux. And since the elected field flux exists, will need this region. We should also remember that the electric field exists only within this region, which has a radius off capital. So our can only go all the way from zero to the capital. I cannot go beyond that in this case. So this means our our artist testicle the one and we get the total net maximum changing and electric flux. So So in this case, we will be using. So, unlike the previous case where the art gets cancelled out this way, in this case, we won't have that our will actually be important. And so a solution will be immuno. Absolutely not. 16 They were both Gupta. This is actually equal into saying no. We can also study the whole case, but is hearing that this is you can also assume that this whole structure is actually a wire so elected feeling. And if I want to find out what's the magnetic field outside, I'll consider the entire current which is flowing through the wire, which is only limited till the surface off the wire. But if I want to find out, elect magnetic field, which is inside the surface off the inside the fire, I'll have to consider it will need that part off the wire, which is in second, and Gary separate, and the solution for this is now good point 13 into 10. Power minus 17 dessler.
