3D motion of flexible ferromagnetic filaments under a rotating magnetic field

Autor: Andrejs Cēbers, Guntars Kitenbergs, Abdelqader Zaben

Publikováno v: Soft Matter

Ferromagnetic filaments in a rotating magnetic field are studied both numerically and experimentally. The filaments are made from micron-sized ferromagnetic particles linked with DNA strands. It is found that at low frequencies of the rotating field
