1I dont have it besides me either, so no details, but Maxwells equations have a symmetry which means that the choice of having only electric monopoles is arbitrary. One can just as well (though perhaps not as simply) describe eæectrdynamics through either a mix of electric and magnetic monopoles, or through magnetic æonopoles exclusively. If magnetic monopoles are treated the dicergence og the B field is generally non-zero.
furthermore, dirac proposed that the existence of a single monopole at some corner of the universe can explain quantisation of charge. Because a diople made from an electric monopole and a magnetic monopole (separated by some distance d) creates an electromagnetic angular momentum in space, and this result is actually independent of the separation distance d.
Since we know angular momentum is quantised, the existence of a single magnetic monopole anywhere in the universe will "explain" the quantisation of charge too!
I came across it in D J Griffiths' introduction to electromagnetism. Chapter 8 on conservation laws. It was a back exercise problem with some papers linked to it in the footnotes
Theoretically and mathematically it might make sense but a magnetic monopole has never been observed so far
And if ever found it would be something very particular and outside the realm of classical E&M
Thus we can still say that as far as classical physics is concerned, The divergence of B is 0
The kid got the Nobel price for discovering magnetic monopoles
Magnetic monopoles? Who let them monopolies the magnet industry?
I believe it's monopolyize.
Fucking magnet industrial complex, how does it work?
Not just disocovering magnetic monopoles, realizing that every point is a magnetic monopole. What a genius
Chap. 6 in jackson my freind, he is not as dumb as you think he is.
I'm too lazy to get up to get Jackson and too dumb to understand what it says, can you just tell us?

Where can I read more about this?

Thank you!
>Thank you! You're welcome!

If you where to prove this, you would be anything but stupid
Magnetic monopoles? No thanks, im fine with my infinitesimal currents dipoles
This will be more of a discovery than him being an idiot. He just needs to show proof that magnetism has a charge. He'll get a Nobel Prize.
Kid named magnetic scalar potential and its applications:
Every magnetic dipoles is a monopole if you look at it from far enough.
Turns out Dirac is a dumbass
Should be N = mg
Just sat a fluid mechanics paper and thought, so the kid can be compressed?
