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

@dandyname
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)?

Preach it to the world brother! I think you’re headed for a Nobel Prize!

There is nothing “wrong” with the video. Left hand rule is for NEGATIVE (electron) flow in a conductor. In electrostatics, the right hand rule for charge flow assumes POSITIVE charge flow. In fact, positive charges are the type used as reference conventions in electrostatics. They “source” the electric field while negative charges “sink” it. For X and DOT field directions, think of vector arrows. X is like arrow tail feathers (pointing AWAY from you). DOT is like arrow tip (pointing TOWARD you).

this is wrong!
its supposed to be right hand thumb rule and all.
its the other way round.
[Reply]
thats what einstein spent his remaining 20 years of life trying to prove and he is right however it’s a little trickier to prove than just stating three sentences with no math. lol
[Reply]
Ah thanks, was slightly confused
[Reply]
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.)

Yes this vidio is wrong at +/- 6:50 min.
X = Clockwise magnetic field!
[Reply]
its the other way around if you were looking at it comming toWARDS YOU ITS ANTI CLOCKWISE THIS VID IS WRONG

ITS THE OTHER w

MY THEORY OF GRAVITY
Gravity is created by electromagnetism created by orbiting electrons of the positively charged nucleus.
There is no such thing as ‘gravity’. Gravity is just the cumulative effect of electromagnetism.
That’s it.
