Hi, in the given problem there are two parallel current carrying conductors which are carrying current into the plane of paper.
00:13
So here these are the symbols for the current getting into the plane of paper.
00:23
Now using right hand thumb rule the direction of magnetic field around both the conductors will be clockwise.
01:08
So if we plot these magnetic field lines around both the conductors, first of all, for this first conductor, this is the first magnetic field line.
01:27
Then the second in the form of a circle and the third and we are noticing the gap between these magnetic field lines will keep on increasing as with the distance the magnetic field strength will keep on decreasing similarly for the other conductor the magnetic field lines in the form of the circles and now when then the magnetic field lines will tend to overlap with each other.
02:11
We know magnetic field lines can never intersect hence.
02:17
Now there will be a common magnetic field around both the conductors and so on and the directions clockwise around both of these conductors.
02:37
Now, in the second part of this problem, we have to discuss the pattern of the magnetic field again, but in case the currents are anti -parallel to each other.
02:52
So, suppose the current in the first conductor is getting into the plane of paper, then in the second conductor it will be coming out of the plane of paper...
