@videoeyer just in time for hsc physics >D
-
This video looks like it was made in Volta's time XD , but it did refresh my memory :)
-
if i saw these videos if i was small, i would be freaked out
-
i taught that its flemming left hand rule and the right hand grip rule.
-
I want this guy to narrate my life.

mmmm donuts...

One could never really understand these things back when we were in school. But your presentation has helped us all get a better picture of things.

@dandyname yea physicist are so naive with particles such as hypothetical particle like gravitons wtf
-
Would you like to specify how electrons orbiting a positively charged nucleus would reproduce results such as Newton's inverse square law? Is YOUR theory of gravity falsifiable (how do you test it)?
nope - this video is correct. It is based on the left hand rule - X represents the electron flowing into the screen. Whereas most textbook would use X to indicate the direction of current nowadays.
(i.e. Electron flow - left hand rule, Conventional current - right hand rule.)

The 'hand rules' always made it more confusing for me. I think its because we already have terminology for this type of thing...clockwise & counterclockwise. I dont see how introducing hands makes this easier because I have two hands and remembering which to use doesnt jive with my brain.
If you're in the same boat, this might help:
The field lines go clockwise if the charge were to flow toward you. (imagine you're in the wire and the electrons are racing at you)
