  • Don't think of magnets: They're weird
  • Think of the magnetic field as the mitigating thing. Don't think of a particle over here moving causing a particle over there to move. It's not intuitive.
  • Later on, we'll see how the Special Theory of Relativity being true creates magnetism, IE, this is really electrostatic forces caused by the speed of light being so slow. (If it were much faster, the magnetic fields would be much, much weaker.)

Hand-waving about how the forces works.

Understanding how it works relies, entirely, on understanding the interpretation of the cross-product.
