Error in magnetic domains image[edit]

I remember my previous physics teacher said that this image: http://en.wikipedia.org/wiki/File:Ferromag_Matl_Magnetized.JPG in the Magnetic domains section is wrong. The arrows should go from north to south. I never really understood his argument so I'm just asking that somebody with more knowledge in this subject take a look at it.

Confirmed: Outside a magnet the lines definitely go north to south. (Inside the B field goes S-->N, the H field goes N-->S.) I corrected the image. (It sometimes takes a day or two before the up-to-date image thumbnail gets put on the page.) --Steve (talk) 14:30, 21 June 2012 (UTC)Subzbharti (talk) 18:13, 21 March 2013 (UTC)

Problem with figure[edit]

Hierarchy of types of magnetism.[7]caption in the diagram are blurred and not readable. Please edit them suitably. thanks — Preceding unsigned comment added by Subzbharti (talkcontribs) 18:13, 21 March 2013

Lead[edit]

I know how hard it is to write the introductory sections for topics like this, and how it tends to generate endless edit wars over minor wording differences. I don't mean to criticize the hard work that has been done on this article. But I feel I don't understand the lead sentence:

Magnetism is a class of physical phenomena that includes forces exerted by magnets on other magnets.

Doesn't magnetism also include forces exerted by magnets on materials which are not magnets? And I'm wondering if the term magnetic field should be introduced earlier, in the first sentence, instead of the 3rd. --ChetvornoTALK 23:32, 19 September 2014 (UTC)

I've tweaked it, hopefully addressing your immediate concern (I agree that it was probelmatic); see what you think. —Quondum 00:09, 20 September 2014 (UTC)
That looks a lot better to me. I like the lead sentence, it a good definition. --ChetvornoTALK 00:27, 20 September 2014 (UTC)

Unified Field Theory and Magnetism[edit]

We adventure into UFT by assuming there is but one source of forces, and that all forces can be explained by characteristics of a space with nothing but relative levels of compression. This means the concept of electromagnetic charge as a characteristic of particles is forbidden.

Mass acquires the definition of an expansion of space, compressing space around it. (Hence it is relative like spacial measurements, and hence it is energy.)

This definition reconciles the strong and nuclear forces rather easily. Two particles of mass that get too close push each other away encompassing the strong nuclear force. The sphere packing of an atomic nucleus, or a star containing black holes, creates suction between its component particles and towards its interior as it expands, encompassing the weak nuclear force. The misshapenness of the compressed space is responsible for gravity. But what is magnetism?

What is magnetism? Why do the same poles of magnets repel and opposites attract? Well, if you spin a massive particle about an orbit you generate a corkscrew shaped object in space time. As two magnetic poles opposite in polarity approach their spin is in the same direction which reduces antagonism from the expanding objects. Conversely, if two magnetic poles identical in polarity approach, their direction is opposite and they plow into each other increasing expansive antagonism.

Magnets, whether the planet earth, a bar magnet, an electromagnet, a gyroscope, all generate their fields through the rotation of mass in the same direction with some preponderance. — Preceding unsigned comment added by GuildCompounder (talkcontribs) 00:19, 1 April 2015 (UTC)
