or maybe I am thinking of the right hand rule applying to electrons.

[forevereternal22]

Is it just me or is the illustration wrong? The equation should be v X B = F. With electrons the left hand rule so... point your fingers in the direction of electron flow. Then curl your fingers toward you palm in the direction of magnetic field flow.  Your thumb should point in the direction of force. However the illistration looks like they are taking B X v = F but this is incorrect. B X v = -F and points in the opposite direction.

Teach your teacher "the middle finger rule"

I've done a similiar video just for the left hand rule on my channel!! Great video, love the graphics!

Do not be silly !!

1) One thing is the magnetic field imposed by the magnet, which runs almost in a straight lines in betwen the magnet poles.

2) Other thing, is the concentric circular magnetic lines around the conductor and produced by the current in the conductor.

3) Where the WIRE CENTERED CIRCULAR LINES go in the same direction as the MAGNET STRAIGHT LINES: magnetism accumulates. Where they go in the opposite direction: magnetism decreases, and form a kind of empty void.

@1091Floyd21 lol physics is confusing xD

Awsome :D>

How come with situations regarding Fleming's left hand rule, the magnetic field lines are always straight instead of curved? The way I see it is; they should be curved. Unless they take the tangent to the curved line as being the direction of the magnetic field. And even if they did this, because a current-carrying conductor may be so long, the direction of the force on the conductor would be different to the direction of the force on the other side of it? I do NOT understand!
