Understanding Gauss' Law and E Fields in Flux Calculations
Hope this helps. Remember: scalar fields don't ALWAYS obey! But that's the way to bet.- HarleySpirit

Understanding Gauss' Law and E Fields in Flux Calculations
In brief, here are two links that will, I believe, make the difference. http://en.wikipedia.org/wiki/Gaussian_surface http://en.wikipedia.org/wiki/Gauss's_Law- HarleySpirit

Undergrad Does magnetic field do any work
Note that we're talking [I]fields[I]. EM fields are stronger than gravity here, depending on temperature. Note also that EM fields have strange effects on superconductors. Why? Magnetic domains like to stay aligned until we heat the magnet, disordering the domains. When we just heat the...- HarleySpirit

Undergrad Does magnetic field do any work
Monopoles to dipoles simplified GUT advocates, please don't give me *that* look: perhaps we have a simpler explanation for monopole/dipole conversion than Dirac and Hawking allow: Rip apart a proton and we see UUD quarks. Couple UD and we have a -1/3 monopole. Couple DD and we have a -4/3...- HarleySpirit

To simplify: http://en.wikipedia.org/wiki/dirac_bracket Wikipedia makes magnetic force a little clearer. Dirac bracket is a bit more direct than your explanation.- HarleySpirit
