why is the Right Hand Rule in electromagnetism true?

Question

Here is a description of the right hand rule – https://www.khanacademy.org/test-prep/mcat/physical-processes/magnetism-mcat/a/using-the-right-hand-rule

I understand THAT this is true, and have even directly seen experimental evidence that it is true, but what i cannot wrap my brain around is WHY this is true.

So please internet, why is the field always to the right?

Answer 1

It depends on the charge under consideration – positive charges right hand rule, negative charges left hand rule. This all comes about because like charges repel and opposite charges attract.
