I hope this isn't in the wrong forum, it's not a problem, just a conceptual question for physics 2.
I have a few questions that I cannot find answer for in my physics book or online.
1) Why does moving a charge parallel to the magnetic field result in zero magnetic force?
Is this quality based on experimental data like the magnetic force equation (something that the book mentions: says the mag-force equation was not developed theoretically, but experimentally)? F = qv x B. I know that due to the cross product, the force will just be 0, but is there another explanation besides just the math?
Why do opposite charges of equal magnitude result in different directions of magnetic forces? Is this a property of the electric fields from the oppositely charged masses (positive are isotropic and negative all point toward the negative charge)?
