So for this question, here it is given the diagram.
00:04
So let us first make a diagram.
00:07
So here we have a square.
00:09
This is i1, this is connected with each other.
00:13
This is i2, i3 and this is i, this is actually b, p and this is d, d, d and d.
00:26
This is connected like this.
00:29
Now at the p, we have a direction.
00:31
The first direction is basically b3 and the downward it is b1 and here we have b2.
00:44
Now it is given that i1 is equal to i2 which is equal to i3 is equal to 2 ampere and d is given as 2 centimeter.
00:55
So basically b1 will be equal to mu0 i1 divided by 2 pi d.
01:05
This is the magnetic field at p due to the current i1 and for the b2, it will be equal to mu0 i2 divided by 2 pi whole root 2 d.
01:19
And similarly for the b3, it will be equal to mu0 i3 divided by 2 pi d.
01:28
This is the magnetic field at p due to the current i.
01:33
Now this is the magnetic field.
01:36
Now our next step, since i1 is equal to i3, therefore the i1 is equal to i3...
