This is all I've got. It can't possibly be right... or could it?

Yep that's correct. You can tell because the "dudelol.com" with a big smiling face and teeth certifies it as correct.

Yup, my thoughts exactly.

It's to do with charges, which are an inherent property of particles. There's really no how, it's just what we observe, there is nothing underlying the principles of magnetism.

It's not fully understood. We have names for the forces involved, but that's about it.

Yay for tautologies.

What do you mean that's about it? There's a whole theory about how it unifies with the weak force, virtual photon interactions and a whole bunch of stuff my second year physics course didn't cover.

Also, if the questioner is interested in how magnets (as opposed to the magnetic force) works, it's got to do with the magnetic dipole created by the angular momentum of the electrons in the atoms making up the substance. If enough of them align in the same direction then you get a magnet. Moving electricity creates a magnetic field. The electrons in the material are 'moving' (quantum mechanics thing) around in circles and so they generate a magnetic field.

Really? I thought it was definitely that gravity thing...

Lol, I realise you didn't mean the thread seriously, but some people evidently read it that way. In which case others might and I thought it would be good not to promote misconceptions at least

I mean we can describe the effects of electromagnetic phenomena, and their interactions with other forces, but we cannot describe what exactly the force is in and of itself. Which is usually what people who ask this question are ultimately after.

If that's your experience fair enough. It isn't mine. We don't really have good metaphysical explanations for anything so this problem isn't limited just to magnetism.

I'd agree. I've just learned that trying to answer this question tends to frustrate both parties, because the scientist puts a lot of effort into explaining what we do know, but the curious party is usually (nine times out of ten) only interested in what we don't know (a good metaphysical explanation). The common question that I encounter ad nauseum is 'yeah, but what is it really?'

The technical explanation is that electrons in the atoms release virtual photons which impart momentum onto another magnetic or electrically charged object.
