"in the magnetic field of a huge horseshoe magnet 0,001 T,"

Hello, is this a typo? Can someone more experienced than I answer?

Sincerely,

Chris

This value 0f 0.001T is pretty low for a "huge" horseshoe magnet. Old fashioned magnets could create field of > 100 gauss, or 0.01T. More modern permanent rare-earth magnets have fields more like 10,000 gauss or about 1 Tesla.

[edit] Definition

The definition shouldn't use the shorthand symbols only; it should have the definition in terms of the names of the units as well, to avoid confusion. --Starwed 20:15, 10 February 2006 (UTC)

And shouldn't the dashes in the various units (like m-2) be the same length? They vary... ~Gertlex 18:02, 23 July 2006 (UTC)

hey.. someone put this in terms someone not taking physics would understand. like.. the amount of 1gram paperclips a magnet could pick up at 1 tesla.

Your example would be measured in webers, not teslas. For tesla examples, see the list of examples in this article. --Heron 21:12, 6 April 2006 (UTC)

Defining all these combinations of the SI units adds nothing to article

>This will continue to occur until the material becomes magnetically saturated and/or the magnetic field >"leakage" increases so fast that no additional tesla gains are possible. [citation needed]

Makes no sense - what is being "reduced"? How does this have any relation to the definition of a unit?

[edit] a large 14 kg loudspeaker magnet will have a coil gap of 1 T

I find this hard to believe, as a tesla is quite a large flux density, so I have tagged it with {{Fact}}. S. Morrow 23:11, 28 October 2007 (UTC)
