Wants to check the power of a magnetQuestionMay 15, 2009 i purchaged one I section magnet, of 300*60*58. i would like to check its power and magnetic field. SO please send me is their any possibilities. suman - India 17748 AnswerYou can use a magnetometer or Gauss meter to measure the strength and field of a magnet. Unfortunately, those are expensive devices. Often a college physics las has one for use of their students. You should put experiments on the websiteQuestionNovember 2, 2008 I think you should do experiments and put it on your website. Ian - USA 16724 AnswerThanks for the suggestion. We are working on putting animated experiments on the website. Can rubber be magnetized?QuestionFebruary 13, 2007 Dear School for Champions, - USA 13146 AnswerThere are some non-metallic materials that can be magnetized, but rubber isn't one of them. To be magnetized, a materials atoms must be able to move freely enough within the structure to line up in the correct magnetic direction. Not only that, but the atoms or molecules must have their own electrons lined up such that the atoms will be magnetized. Does copper have a magnetic property?QuestionMay 17, 2006 Does copper have any magentic property ? How can copper help in magnetising the water if we add CuSo4 to the water ? Ameet - USA 11135 AnswerCopper is considered paramagnetic, meaning that it weakly responds to a magnetic field. See: Temperature and magnetismQuestionApril 21, 2006 I would like to know how a lower temperature affects the magnetism of an atom. Ebony - USA 10904 AnswerThe magnetism of a material is when the atoms are aligned. High temperatures cause them to be misaligned. Also, a lower temperature slows down an atom and allows its field to appear stronger. How does heat affect magnets?QuestionApril 1, 2006 how does heat affect magnets? and can you explain it fully? thanks harrison izzy - USA 10721 AnswerMagnetism is due to the atoms or molecule lined up the in the orientation. The greater the heat, the more motion they have, thus causing them to point in various directions and reducing or eliminating the magnetic effect. Does heat affect magnetism?QuestionFebruary 1, 2006 what effect does temperature have on perminate magnets. Is a magnetic field stronger while in a cold environment? alexander - USA 9893 AnswerHeat can reduce the magnetic strength. It can ruin inexpensive magnets. The reason is because the magnetic field has to do with the atoms lining up in the same direction. Motion from heat disorients the atoms. Does temperature effect the strength of a magnet?QuestionMarch 8, 2005 does temperature effect the strength of a magnet? - USA 6261 AnswerIncreased temperature decreases magnetic strength.
