Hello,
The Lorentz force equation, F = q (E + v x B), is a complete description of the force on bodies arising from Magnetism and Electricity, right? So somehow it must be possible to get from the magnetism that exists in materials (like in a magnet) to this equation. I don't see how the connection can be made. How could one get from having a magnet that always gives off a magnetic field that will cause a force on a piece of steel to this equation which has the velocity of charges? Is there a velocity of an electron in the magnet that will make this all work out. I am guessing that because of the bizarre nature of electrons the answer would be no, so how can one explain the nature of magnets with this equation.
And another question is how in how in heck did they make sense of this connection from magnets to this equation back in Maxwell's time when they didn't even know that an electron existed...?
Anyway, insight into this would be greatly appreciated. Thanks! -xerxes73
