There are two parts of the equation.
00:02
In the first part, again there are three different subquations are there.
00:07
Let us find the first one.
00:10
There they have given three different diagrams and in these diagrams they indicate the direction of electron flow and there we have to find the magnetic field direction.
00:24
So here the first diagram is this is the conducting material.
00:33
And this is the flow of the magnetic field direction.
00:44
This is the magnetic field direction.
00:47
Here we have to use the right hand thumb rule.
00:51
There the thumb indicates current.
00:56
Just imagine right hand thumb rule and there the thumb indicates the current direction and curled fingers indicates the direction direction of the magnetic field.
01:19
So here the direction of the magnetic field is in the direction of anti -clockwise so that the thumb indicates towards the left.
01:34
So this is the direction of current.
01:42
And in the second question there is another diagram.
01:48
Again there is a conductor and this is the direction of magnetic field...
