Though it is easy and interesting, we never tried it out seriously. A junior member insisted to go for it and volunteered to do the field job. Getting into sandy bed, carrying magnets, searching for iron dusts in the sands, segregating the dust from common dust, cleaning those up, and then putting them under Microscope.
Out of over 10 grains tested, I have found two to be possible meteorites as those were found to be carrying bllister marks, a definite sign of its being a Micro meteorite. During its entry into earth atmosphere at a velocity of around 30 – 80 KM/ Second, it attains at very high temperature and starts boiling in itself. When dries up, the dried up and solid boiling marks become the signature.
With magnetic process, we can only look for the iron containing Micro meteorites only. Best place to look for this is ones flat rooftop, sandy river bed etc.
