| Research Abstract |
A new method to identify the material of a small grain is proposed which is driven by magnetic volume force. By comparing the measured susceptibility of a particle by their published values, material of the particle is identified. Solid materials are generally obtained as an ensemble of grains with different elemental composition with heterogeneous origins. At an initial stage of investigating this type of material, it is important to extract and identify the material of individual particles included in the ensemble. Such method should be non-destructive and easily performed.. The present results achieved on sub-millimetre-sized diamagnetic grain have a large significance as a step to realize the extraction and identification of micron-sized grains that compose the primitive materials. The technique described is useful in the search for new types of pre-solar grains that are not identified as yet.
