@Metal-Brain
Two things. One, every atom has a magnetic field, tiny as it may be.
If they are all jumbled up they add up to zilch.
If you can get all those tiny magnets to line up then you have a useable external field made up by all those tiny ones acting in accord.
The second one comes from moving electrical currents in a conductor.
If you have an electrical curre ...[text shortened]... or.
Not sure how I can make it simpler than that. Anyone else willing to try, knock yourself out.

"every atom has a magnetic field"
Why? What is a field?
@kazetnagorra saidJust tell us you do not know.

@sonhouse saidNot all elements can be used to create permanent magnets. Just Iron, nickle and cobalt.
@Metal-Brain
I bet you have a LOT to say on that subject.
@sonhouse saidYou cannot make a permanent magnet out of any element or even every metal element. Why is Iron, nickle and cobalt the only elements that can be used to create permanent magnets?
@Metal-Brain
The truth is every element has some magnetic moment, some small some large. You can attract OXYGEN molecules to a magnet if the field is strong enough.
Frogs have been levitated in high magnetic fields.

@humy saidEven if you add 1 to 4 you still have a limited mount of elements. Why?Why is Iron, nickle and cobalt the only elements that can be used to create permanent magnets?
This is simply false. Although not all elements can be used to make a permanent magnet, more than 3 of them can. And the only reason why those certain other elements other than Iron, nickle and cobalt aren't used is because of a combination of;

@metal-brain saidWhy not?
Even if you add 1 to 4 you still have a limited mount of elements. Why?
@humy saidSo you are incapable of explaining why. You do not understand what causes magnetism.
Why not?
Why not, just like I previously asserted, have only some and not all of the elements that can help make a permanent magnet?
What's your point?
@metal-brain saidExplain your understanding of what causes magnetism...
You do not understand what causes magnetism.
@humy saidI never claimed I understand it. Why do you think I created this thread? Look at the title of this thread. Notice the question mark.
Explain your understanding of what causes magnetism...
@bunnyknight saidI agree.
@sonhouse
My gut feeling is that nobody, not a single scientist on Earth, really knows what magnetism really is. It's just as mysterious as dark matter or dark energy.
