Needs a good explaination of the physics
editA good explaination of the physics would be helpful. I've provided some links as a starting point, but I'm not qualified to write on the physics of this obscure effect. --John Nagle (talk) 18:12, 15 December 2007 (UTC)
- I've edited the article a little. The IBM reference specifically states that the Edison patent does not involve this effect, only resembles it, so I removed the claim that it was the first use.
- Although a device disclosed in a patent3 issued to Edison in 1879 does not depend upon the Johnsen-Rahbek effect for its operation, it nevertheless resemblesa Johnsen-Rahbek clutch
- I also changed the basic definition: the effect creates an attractive force between the two surface. This has the side-effect of increasing the frictional force, but could have other consequences as well. I used this paper as a reference, as well as the IBM paper already mentioned. It contains some more info about the exact physics behind the effect, should anyone wish to pursue that, but I just skimmed it. --Starwed (talk) 13:33, 21 May 2008 (UTC)
- Due to some reorganisations the first link to the IBM article is not active any more. The new link is http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=5392717&url=http%3A%2F%2Fieeexplore.ieee.org%2Fstamp%2Fstamp.jsp%3Ftp%3D%26arnumber%3D5392717 Howewer download or access to the pdf costs as much as $ 33- --178.38.5.35 (talk) 11:15, 14 March 2016 (UTC)
