Can somebody just explain magnetism for me.

I think I get electricity, because different charges attract one another and this can be identified in field form by looking at all the charges, and how they would effect another particle placed in the system.

So how the fuck does this produce magnetism? Why are electricity and magnetism actually connected? Why are some substances "magnetic" and stick to fridges and shit seemingly at random?

Holy moley! That does look like that! And shards of metal aren't aware they're being attracted toward magnets, are they?

Okay, let's say I just accept that magnetism gets generated when electrons are running around and changing the electrical field. What is the justification for changing magnetic fields to generate electrical fields? That is, why do magnetic fields make electrons start moving around?

Atoms have charge, most materials have chaotic charge patterns that cancel eachother out. Some materials have their charges aligned and this allows electric fields to develop along the charge lines. Magnetism is when these fields interact with eachother and either attract or repel.

That is one of the axioms of electromagnetic theory. Its justification is that the theory accurately describes reality.

I think I'm starting to get it. What is that a picture of? Are the completed hexagons aligned charges?

It's more accurate to say that a magnetic field IS a moving electric field. Or, it's an electric field in a different frame of reference.

>So how the fuck does this produce magnetism?
A moving electric current carries a magnetic field. It's an intrinsic quantum property of the subatomic particles themselves (called spin). In relativity, electric and magnetic fields are the same thing (simplification) depending on the viewpoint of the observer.
>Why are electricity and magnetism actually connected?
Why is pi 3.14? It is, and explanations of electrodynamics seeks to model and explain how, not primarily why.
>Why are some substances "magnetic" and stick to fridges and shit seemingly at random?
In most atoms, the subatomic particles are arranged in such a way that all the tiny magnetic fields from each subatomic particle cancels out overoverall. But in some materials however, the subatomic particles line up in a particular configuration so the field doesn't cancel out - which gives them a magnetic field and causes them to 'stick' to other things.

He's talking about muslims specifically when he says sandniggers. He's also referring to the kaaba when he says black rock. Where else would he get the correlation from?
