This article deals with magnetic cooling working near temperature rooms. The author identified and described in details  a number of properties concerning the work of magnetic coolings. Working body cycles, the ways of creating and magnetic field converting , and also the ways of heat transfer between the working body and heat exchangers can be refered to such characteristics. It should be stressed that the properties obtained gave way to present a systematization of magnetic coolings working near temperature rooms. The given systematization will help significantly to reduce the time which is necessary for magnetic coolings patterns developing with the required characteristics such as temperature difference and cooling capacity. It also should be emphasized that this systematization will reveal advantages and disadvantages  of these magnetic cooling patterns
