Electron moves in the positive x direction and at point d in the xy plane what is the direction of the magnetic field caused by the electron.
00:11
Okay.
00:12
So remember that the direction of the magnetic field will be given by the right -hand rule, right? so the magnetic field because of this electron, since this electron x as a as a as a charge since it is moving.
00:34
So basically that's a current moving and the direction of the current is going to be exactly opposite right because the direction of the current is exactly opposite to that of the electron.
00:43
So using the right hand rule, if we take a right hand and put our thumb towards the direction of the current, then basically the curly fingers will give the direction of the magnetic page.
00:56
So if we put our hand like this, the curly fingers are coming out of the page in this at this point.
01:02
So it is a it is directed towards the plus xx because that is directed above out of the page.
01:10
Then what would be the direction of the magnetic field of the electron moved towards negative x -axis? so if it moved towards negative x -axis, then definitely the current would have been over here.
01:20
Then using the right -hand rule, that would have been into the page, into the page, into the page means minus the x -ex, exactly opposite...
