Why are there no magnetic monopoles? is there. Is there a physical explanation or is it just a fundamental property?

Anonymous No. 16166749

There is some theory on the properties of a hypothetical magnetic monopole. But, a magnetic monopole has not been experimentally confirmed. Magnetic fields are formed from the motion of charge. In general, Maxwell’s equations tell us that magnetic flux must always be conserved through any closed surface, therefore, it is in the shape of a loop and cannot be a source or sink. There are many ways to experimentally determine this.

Because the traditional view of magnetic fields is that of a line, when in reality it is a sphere. You can't have half a sphere, that's silly.

Wouldnt it make more sense if the magnetic and electric field behaved the same? what is preventing the magnetic fields from having a source or a sink like the electric field? I understand the math that follows from maxwells equations but is there any explanation for why they are what they are besides experimental evidence?

There very well may be magnetic monopoles

There are electric sources and sinks because charge is a fundamental property of particles, where positive is typically a proton and negative, an electron. Therefore, we can have net positive or negative charge. There isn’t an equivalent particle for magnetic fields which either has net “north” or “south”. Instead, magnetic fields arise in closed loops when charges move. I’m thinking you’d violate conservation or charge or energy if you started violating conservation of magnetic flux. But, I am not an expert; just an EE.

There is no such thing as a magnetic "pole," mono- or otherwise.

The conventional images of a "magnets," like bar magnets and solenoids, are an illusion. The real magnetic phenomenon is the flux loop, which conveys speed- and momentum-like information similar to a flywheel.
Asking why there are no monopoles is like asking why there's no East without a West, no North without a South. Magnetism is fundamentally a direction.

What is spin (as a quantum property)? Honest question.

Reminds me of some kind of configuration that was *almost* monopole.

You should note that magnetic monopoles do exist at ∞. And much like black holes, we can make up a bunch of bullshit at this boundary condition.

If there were, magnetic spin wouldn't be an intrinsic properly of particles.

All intrinsic properties of objects tell you, loosely speaking, how that object responds to fields. You name a field, and I'll name the intrinsic property related to it
>Gravitational field yields mass
>Electric field yields charge
>Magnetic field yields spin
There are quantum fields (qft) as well
>Electroweak field yields isospin
>Qcd field yields color
>Highs field yields gauge boson mass
And so on. Spin is to magnetic field as charge is to electric field.

it's more of an observational fact
lots of theorist would like them to exist

More like a lot of perpetual motiontards would like them to exist. But they can't, because that's literally not what magnets are. See >>16166781

i use magnetic charge, magnetic current, and magnetic dipoles extensively in advanced electromagnetics
there is nothing inconsistent in maxwell's equations with modeling those things
they just don't appear to exist from observational data
as far as we know, all magnetic phenomena are attributed to electric currents

So the spin of an electron is an electric current?

Not necessarily - remember that the magnetic part of an electromagnetic field (as far as we currently understand it) is an exclusively relativistic phenomenon, and that part of the interaction is only present if there is some relative motion involved in whatever is generating the field and whatever is interacting with the field, whereas the electric part of the dynamics still exist whether there is relative motion or not. It's not necessarily unsurprising, then, that they don't follow *quite* the same behavior.

i thought of quantum magnetic dipole moments 2 seconds after submitting fuck face
people tried in vain for years to describe that shit classically as an electric current, with varying success
