However, it can also be designed as a whole as a cigarette or cigar tip, or it can be designed as a tubular filter element integrated into the mouthpiece side of a cigarette or cigar. Due to the inventive arrangement of a pipe or ring element made of ferromagnetic material, in particular ferrite, with an inserted permanent magnet, the tobacco smoke passes through a magnetic field on the way from the cigarette, cigar or pipe bowl to the smoker, which has advantageous effects on the pollutants contained in the smoke. This is based on the following: A permanent magnet creates a magnetic field. This is done by introducing ferromagnetic material, for example
  • Ferrite concentrated, i.e. bundled, and creates local reinforcements of the magnetic field lines, whereby the magnetic forces are significantly increased.
  • tobacco smoke containing particles flows through this concentrated magnetic field, particles are held in the field and deposited and thus do not reach the

  • the wall thickness of the tubular insert can preferably be 0.2 to 0.4 mm at least in the area of the magnet section. But it can also be made thicker.
  • a ferrite with an initial permeability ⁇ j of at least 1,000, preferably of at least 1,800 (at 200 kHz) is particularly suitable for producing the tubular or ring element or the insert from ferrite.
