The synthesis of nanostructures with carbon nanotubes 
in a plasma reactor with a high-voltage atmospheric-pressure discharge 
(voltage 1-4 kV and current to 200 mA) on exposure of the discharge 
to an external magnetic field with an induction of 0.03 T or higher 
has been investigated. The composition of the soot products has been 
studied. The discharge was initiated in a quartz channel between the 
electrodes from catalytic metals in an atmosphere of hydrocarbons 
mixed with air. The nanotube yield in the soot product amounted to 
10-70%. On imposition of the magnetic field, the yield increased 
by 10-30%, all other things being equal.
