The Right Hand Rule and the Magnetic Field Straight Wire

[meganewbies]

I think that something is wrong in this video, because the hand rule is completely false!

Thanks for this, But this one is very easy, i would prefer you to explai RHR2 if you did not already because i did not check.

Thanks once again.

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!
