Toys: Given their ability to counteract the force of gravity at close range, magnets are often employed in children's toys, such as the Magnet Space Wheel and Levitron, to amusing effect.

A specific MToH embodiment DOES employ magnets (see picture in the article withe the caption "An illustration of the analogy to magnetism: Disks repel each other if their touching sides have the same color"). Magnetic disks make, I think, an exciting playing effect ("announcing" illegal moves). And if you spin a "hanging" disk, it will rotate quite long (tens of seconds depending on its size of course), around the post. A rather uncommon scene.

I'm not sure how they work. I tried reading the article but i don't understand anything at all. Can someone please explain to me how they work?!?! I have this thing for school but i dont even know how magnets work. I asked someone but they said cant tell if just stupid or trolling but i dont know what that means please help. this website said something about it but i dont understand pleeeez help

Here is a piece of wisdom for you:
MAGNET, n. Something acted upon by magnetism.
MAGNETISM, n. Something acting upon a magnet.

Feynman's discussion is great!! And can't find "Microscopic origin of magnetism". But What we have is a discussion of the microscopic forces holding things together and aligning them. Then there are discussions about the existence of randomly oriented domains or small volume parts of a magnet, and then what is lacking is an admission as to the existence of a spacial substance that is capable of extending these internally generated forces into a larger volume of space than that of the magnet. And so to explain this factual occurrence we resort to mathematics to generate a concept and rationalize the distance requirements appropriately. WFPM ( talk) 17:48, 15 February 2012 (UTC)

There is no defination for magnetism . Magnet re used in our daily life . If magnets were not there we would not be able to see television. Magnets guide electrons to the screen . In olden times there were many theory about magnetism . Some say magnets were first found ,When a boy was walking with a metal rod in his hand suddenly it got stuck with a stone then it was named a magnet ,it was named a lodestone .It was found in Magnesia which was in Greek .It was found 2500 years ago . In that time it was mostly found in Greek,China and India . Today magnets are used in our daily life from television to Medical uses . ( Hamza52 ( talk) 13:27, 31 July 2011 (UTC)).
I realized that, with so few citations, this article doesn't even meet the first criterion for a B article: "The article is suitably referenced, with inline citations where necessary." I added several references after I started this section, but it was hard to find them for all the technological applications. It would really help if the people who put the content there provided the references. RockMagnetist ( talk) 04:04, 15 October 2011 (UTC)

is there any way we can shield magnetic effect from attracting other ferrous metal around it? — Preceding unsigned comment added by Muddasir shaikh ( talk • contribs) 13:21, 9 February 2012 (UTC)
I recently made some significant changes to the lead of the article to the following ends:
These changes were reverted with the rationale "I feel the original wording was clearer for nonscientific readers, emphasizing that ferromagnetic materials both make up magnets and are attracted to them".
I disagree with this: the whole point of these changes was to make the lead more accessible to inexpert readers, and to avoid the common problem whereby our article leads focus on minutiae to the detriment of general concepts. Moreover, it would seem that only minor changes would be required to address the problem mentioned, rather than a wholesale revert.

My wife and I came here because she wondered about the history of magnets. I had explained the compass needle thing, which she didn't know. So, this talks about early compasses but it says nothing about the manufacture of magnets, when the first "synthetic" magnets were devised, and through the newer types of magnets. I don't know this, I just think it would be useful and even more useful than some of the things that ARE there. Just a thought. Jjdon ( talk) 20:30, 10 October 2012 (UTC)
This has very little about unpaired electrons (what makes something a magnet). i searched the page for 'electron' and the browser found
Electron configuration but nothing there either. I googled and found the unlinked wiki page
Unpaired electron (i cannot link it in the Magnet page as it is locked), but it does need a little improvment. Are there fewer unpaired electrons once iron atoms are in a lattice? From my own research Fe2O3 is quite magnetic but when that was put in water the now FeO(OH) is not.

I have recently been revising on magnetics and would just like to say how informative and easy to read this article is. It is packed with information and progresses from the basics to the mathematical complexities so that you can choose your own level. Obviously a lot of work has gone into the preparation.
May I suggest though that it would be an enhancement if a list or table could be included showing example magnets from the entire range of strengths: (1) earth's weak magnetic field. (2) fridge magnet. (3) normal high power magnet (loudspeaker magnet for example). (4) most powerful man-made magnet. (5) fantastically powerful magnets of astrophysics. The full information is here: /info/en/?search=Orders_of_magnitude_(magnetic_field) , which I also suggest could be linked to from this article.

History of Magnet and earth gravity: Middle East Ikhan Al Safa "أخوان الصفا" were a group of philosophers in the Middle East. Around the 10th century, they published 52 messages culminating the science and philosophies of their time. In their fourth message "Mathematics Section: Geography" they explain that the earth is a sphere that stands at the center of air sphere, which they believe surrounds earth all around. They explain that the reason why the earth is at the center because "the center of earth pulls all earth parts all together... The center of earth is the center for all spheres, it is the magnet of all weights... Thus the earth retains its round shape, because in the depth of this center this magnet is keeping earth and all the spheres around earth still in the center" (رسائل اخوان الصفا وخلان الوفا، ٢٠١١، المجلد الثالث، دار صادر بيروت، الرسالة الرابعة، ص. ١٦٢).
They continue to explain how earth's mass is much heavier than water, and that is why water floots on top, and that air's mass is lighter than water, and that's why it is on top of water (p. 162)
-personal note: These books have been banned in the Middle East for Years, because Muslims believed these philosophers were hectic. However, I hope we can collectively grant them recognition for their attempts to enrich science and humanity. 2601:406:5000:B440:B16E:1025:AA07:AD17 ( talk) 22:06, 5 June 2022 (UTC)
