The resolution of a set of magnetohydrodynamic equations governing the ejected matter, under some simple assumptions, leads to the existence of a magnetic field about 10-3 - 10-4 G within the shell of planetary nebulae. The stellar magnetic field, at the time of ejection, is supposed to be equal to 1 G. The condition H2/8 π very large nkT is then satisfied in most of the planetary nebulae showing 'magnetic' features such as NGC 650-1, NGC 7293, etc.
