Hi, there are two straight parallel current carrying conductors which are kept perpendicular to the plane of paper.
00:11
This is conductor 1, this is conductor 2, and both are carrying a current, the same current is carried by them and that is coming out of the plane of paper perpendicularly.
00:26
Here this is the line joining them.
00:29
And this is a perpendicular bisector shown in the given figure.
00:36
Now, the distances each 10 .0 meter, this is also 10 .0 meter and here, this is also 10 .0 meter and here this is a point p, an observation point p, at which we have to find net magnetic field due to these.

Two current carrying conductors so if we look carefully here if you look at the upper right angle triangle as these two sides are same and meter each so it will be an isoscelis right angled triangle so these two angles will be 45 degree each this one and this one similarly here the lower angle that will also be 45 degrees so ultimately the complete angle this combined angle will be 90 degree now using right hand thumb rule the direction of magnetic field at point p due to the currents in wires at locations 1 and 2 are as shown in the figure so if we draw these magnetic fields in the figure here this will be the magnetic field due to the current passing through wire 1 so let it be b1 and here this will be the magnetic field due to the same current in wire 2 so we name it as b1 b2 and these two are having an angle of 90 degree between them...
