An efficient and convenient way to levitate and manipulate micro beads is reported, in which coils and soft magnetic materials are used to generate a magnetic field. The levitation is based on diamagnetic buoyancy, and the main structure of this device is made into spiral switch arrays so as to simplify the interconnection and magnetic field control. The design, modeling and fabrication of the device for manipulation of diamagnetic beads is given in detail. Theoretic analysis and experimental results of fabrication indicate the advantages and feasibility of the proposal illustrated here.

The Magnetic Field

The aim of this work is the development of an electronic device for the rapid characterization of soft ferromagnetic materials for electrical purposes named singlesheettester(sst). The basis of this study consists in determining the magnetic induction, B and the magnetic field, H, by using a simplified circuit. Results are compared with classicalepsteintest and the obtained losses present an error less than 10%.
