[edit] Diamagnetically-Stabilized Levitation

A permagnet can be stably suspended at room temperature without either servo control or superconductors
by various configurations of strong permanent magnets and strong diamagnets. When using superconducting
magnets, the levitation of a permanent magnet can even be stabilized by the small diamagnetism of water
in human fingers.

This bit looks nonsense, especially as it seems to either contradict other stuff in the article, or be totally redundant depending on how I read it. I'm moving it here in case anyone wants to comment on it...

It's a real effect, though poorly written. reference that says almost the exact same thing — Omegatron 23:21, 8 June 2006 (UTC)

[edit] Levitation of aluminium

Many years ago on british children's tv I saw a large and heavy telephone book being levitated. It was then explained that this was due to an aluminium plate hidden within it.

If you could remember the name of the show and other information, that might be notable enough to include in the article. — Omegatron 22:31, 10 June 2006 (UTC)

[edit] Edit as 22.10.2006

Hi, I re-inserted the section on electrodynamic suspension, not sure why it was removed as it is an important principle. PLease give reason why it should not be in.

[edit] equation

I don't understand the equation at all. What "minimum criteria" is this measuring exactly? Minimum mass? Minimum volume? Minimum diamagnetic field? What exactly is measured in T-squared over m? The examples of water and graphite are no help since you do not explain how you reached the figures involved. Nor do I understand what >> means. Widsith 15:21, 4 September 2007 (UTC)

[edit] Inductrack

There's a lot of advertising for Inductrack here, should this be mentioned by name in the main article or just linked to or what? —Preceding unsigned comment added by 129.215.188.108 (talk) 15:15, 5 September 2007 (UTC)

[edit] Possible to create an aircraft supported by mag lev alone?

Is it possible? 64.236.121.129 15:58, 3 October 2007 (UTC)

No, A Maglev Vehicle would need to be held steady by an upright force from an electromagnet, Meaning, the aircraft would be stationary on the ground (Or moving, but thats a train) 89.242.174.104 (talk) 19:37, 31 March 2008 (UTC)
