All right hand rule problem.
00:02
So it says an electron, so let's draw this, an electron, this is negative charge, moving west.
00:10
So i should probably read the whole question before i start drawing things, because i would need to put it over on this side.
00:16
So an electron moving west enters a magnetic field.
00:21
So here's a magnetic field.
00:26
Right.
00:27
And because of this electron, because of this field, the electron curves upwards.
00:30
So this electron is going to go like that.
00:35
We may conclude that the magnetic field must have a component what? so right hand rule.
00:40
So again, the right hand rule, right? the way i do the right hand rule is take your hand, your thumb, and your four fingers, right? my fingers are going to represent the field, and my thumb is going to represent the velocity vector...
