        Possibility of relationships between catalytic activity on the one hand and magnetic fields and magnetic properties on the other, has interested many workers.  It cannot be denied that those chemical elements that show the most pronounced catalytic activity, namely, the transition group elements, are also the elements that show the most interesting magnetic properties.  In at least 1 case, the ortho-para-H₂ conversion, there is a clean-cut relationship between magnetic moment and catalytic activity.  This is not to say that all catalytic activity is due to magnetism.  It may yet appear that catalysis and magnetism are different manifestations of some more fundamental atomic property.  But for the present, the chief applications of magnetism to catalysis are in structural studies of catalytic solids.  A review of such applications and of certain related effects is the purpose of this article.  Susceptibility data are included for some substances of major catalytic interest.  222 literature refs.
