Nandric,
these particles sits quite tight on magnet, I so they are magnetic ones. Cartridge works like magnetic filter of dust or debris. As Ikeda magnets sits even closer to dust (surface) it filters more material.
It can be seen in electromagnetic cartridge you can remove them just by blowing so they are not sticky like glue or electrostatic by their nature.
