The results of theoretical studies of the magnetization of single-walled carbon nanotube metal type with regard to the electron-electron interaction in the approximation of a right circular cylinder are presented. The explicit form of the dependence of the magnetization on the temperature and the chiral index. The analysis of dependence showed that the increase in temperature of the object corresponds to the growth of the magnetization. This result can be explained by the increase in molecular circular currents with increasing electron temperature. The analysis of dependencies installed for the type of «armchair» nanotubes and like «zigzag». Nanotubes such as «chair» have greater largest magnetization than the tube of the «zigzag» of similar diameter. Thus, with increasing index m chiral magnetization tends to decline. In the course of this theoretical study found that the decline takes place more smoothly than the zigzag chair for structures. With increasing electron temperature study of nanostructures, there is the absolute value of the magnetization growth. However, the downward trend of the magnetization with increasing chiral index is maintained. The results are compared with the currently available concepts of magnetism of carbon nanostructures. It was found that the nanotubes chair and zigzag modifications have no magnetization in excess of the value of the chiral index values hundred units.
