ABSTRACT:
A method and apparatus are provided enabling a magnetically-responsive substance to be contained in a well formed in a non-magnetic material and viewed through a light microscope while subjected to a magnetic field established either by an electromagnet or permanent magnet source. After the observation, the invention also provides means for preserving the observed specimen on a coverslip used to form the well.
