In this question here, a part is, so here in a part using the right hand rule, using the right hand rule, right hand rule.
00:18
So, figure should despite the direction of flow of current, that is, and the thumb would depict the direction of magnetic field.
00:28
So there is another way to determine the direction of the magnetic field.
00:35
That is, imagine that you are the right end of the solenoid.
00:41
So here imagine that you are the right end of the solenoid from that point of that point of view.
00:58
So the direction of the direction of current would be in the anti -clockwise.
01:16
So here direction indicates the north pole of the magnet.
01:22
So here the direction indicates the north pole of the magnet.
01:31
North pole of the magnet and similarly if you were facing the right end of the magnetic field so here similarly if you were facing the right end of the magnetic field you would see the current flowing in clockwise direction clockwise direction and that would indicate the south wall and that would indicate the south hole.
02:09
And that would indicate the south hole.
02:14
So as we can see from the diagram that the magnetic lines go from north to south outside the solenoid and from south to north inside the solenoid...
