Zusammenfassung:	The magnetic properties of a nanotube are investigated using a model in which the helical symmetry of the nanotube is governed by an extended δ potential. The magnetic moment of the system is studied as a function of the magnetic flux. It is demonstrated that the equilibrium magnetic moment at a large amplitude of the δ potential is a smooth function of the magnetic flux. An expression is derived for the magnetic moment induced in the given system for the case in which the electron current in a ballistic regime passes through the system.
