'Magnetic Flames' In Molecular Magnets Exhibit Properties Similar To Fire - Story from SpaceDaily.com (http://www.spacedaily.com/news/physics-05zh.html)

"In a groundbreaking experiment, researchers from The City College of New York (CCNY) and Lehman College have measured the speed of magnetic avalanches and discovered that the process is analogous to the flame front of a flammable substance.

Yoko Suzuki, a graduate student at The City College... observed that the avalanche began at one end of the crystal and propagated at speeds of a few meters per second in the form of a "flame" front that released magnetic energy into the crystal."

Does anyone think that these findings might have implications for studies of stellar and/or planetary magnetodynamics? :huh:

Hi Cran,

I think it could be very important, if only I undrstood what they are telling. Magnetic flame? Magnetic burning? Hall sensors? I need to read up on this, are there any sources that you know of?

Cheers.

A Hall effect sensor is a semiconductor that ouputs a variable voltage, dependant upon magnetic fields going thru the sensor.
