If a = supercooled chunk of iron, passes thru a magnetic field then internal = currents would be set up which would be sustained by the fact that the = alloy may be superconductive at this temperature. I really need a physicist to unpack this for me! But it seems possible that the effect of this superconducting mass of = metal would have a number of effects - for example, each lump would have = a magnetic field around it, which would induce currents in the other = masses nearby and so on. How would this phenomenon express itself as the mass came crashing into = our atmosphere? So many questions! Not too sure that I have expressed this issue very clearly, but I am = sure someone on the group will be able to see where I am coming from on = this! --=20 In gentle decay,=20 d.=20 =20 http://www.meteorites.ic24.net/index.html =20 "I have a proof that x^n+y^n=3Dz^n never has integer solutions for n>2.=20 However, it won't fit into my signature file...."=20 =20 ------=_NextPart_000_0018_01C0B61F.259F1D40 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META content=3D"text/html; charset=3Dwindows-1252" = http-equiv=3DContent-Type> <META content=3D"MSHTML 5.00.2314.1000" name=3DGENERATOR> <STYLE></STYLE> </HEAD> <BODY bgColor=3D#c0c0c0> <DIV><FONT face=3DArial size=3D2>Hullo,</FONT></DIV> <DIV><FONT face=3DArial size=3D2>Just a thought I had the other day re = the fact as=20 that meteoroids spend most of their time cooled to just above absolute = zero as=20 they fly thru space, I thought that there may be some physical effects = due to=20 the superconductivity of the Fe/Ni alloys that they are made of. = If a=20 supercooled chunk of iron, passes thru a magnetic field then internal = currents=20 would be set up which would be sustained by the fact that the alloy may = be=20 superconductive at this temperature.</FONT></DIV> <DIV><FONT face=3DArial size=3D2>I really need a physicist to unpack = this for=20 me!</FONT></DIV> <DIV><FONT face=3DArial size=3D2>But it seems possible that the effect = of this=20 superconducting mass of metal would have a number of effects - for = example, each=20 lump would have a magnetic field around it, which would induce currents = in the=20 other masses nearby and so on.</FONT></DIV> <DIV><FONT face=3DArial size=3D2>How would this phenomenon express = itself as the=20 mass came crashing into our atmosphere?
