Same reason you can't cut a string and get two strings, each with one end!
Can you really make free energy with a magnetic monopole?
Fucking hell you are dense. It's an empirical observation.
Don't listen to this retard, bar magnets aren't the only magnetic fields.
[math]\nabla \cdot \mathbf{B} = 0[/math]

When you can produce a magnet where the field lines don't form closed loops (they don't end at the poles, you know. They continue right though the magnet) THEN you can call others "retards".
Until then, shut up and go back to /x/.
Or learn basic physics.
I was talking about your shitty "explanation", there's no more fundamental property of the universe (we know off) that makes the magnetic field have divergance 0, so theoretically it's not excluded by anything besides our observations. Non of that implies that I beleive in magnetic monopoles and free energy bullshit, but rather that explaining a "why" of a Law only makes sense if there is a deeper thing in the fornalism. In classical electromagnetism, you have to start maxwell equations, so you cannot explain why.
Also, it's a big misconception that magnetic field lines must form closed loops, the only requirement is that the diverance of the field is 0.
>field lines must form closed loops
if they didn't the electron flow would stop. think about it, if you only had one pole of a magnet you would lose all the electrons out without them having a returning point no push and pull motion just push or pull, continuously until the force is depleted.
Not every magnet is a bar magnet ffs. Check the field generated by circular circuit that is bent just a little outsude if it's plane. What there aren't are sources or sinks. The lines can wind around forever without closing.
We can't make free energy with an electric monopole, so i don't see why we should be able to do it with a magnetic monopole (if it existed)
It's already free energy. Where does the electrical current from a dynamo come from?
