What happens when you put a frog inside a 16-Tesla magnetic field at the Nijmegen High Field Magnet Laboratory? It levitates! In fact, it is possible to levitate magnetically every material and every living creature on the earth due to the always present molecular magnetism. The molecular magnetism is very weak (millions times weaker than ferromagnetism) and usually remains unnoticed in everyday life, thereby producing the wrong impression that materials around us are mainly nonmagnetic. But they are all magnetic. It is just that magnetic fields required to levitate all these "nonmagnetic" materials have to be approximately 100 times larger than for the case of, say, superconductors. http://www.hfml.ru.nl/froglev.html | Gallery of Levitating Objects (Thanks Tony!) |
