Magnetic forces produced by rectangular permanent magnets in static microsystems
Hubert Girault, Joël Stéphane Rossier, Anne-Laure Gassner, Mélanie Abonnenc, Hong-Xu Chen
Finite element numerical simulations were carried out in 2D geometries to map the magnetic field and force distribution produced by rectangular permanent magnets as a function of their size and position with respect to a microchannel. A single magnet, two ...
2009Dispositif de manipulation et de transport de perles magnetiques
A device for transporting magnetic or magnetisable microbeads ( 25 ) in a capillary chamber ( 14 ) comprises a permanent magnet ( 10 ) or an electromagnet ( 11 ) for subjecting the capillary chamber to a substantially uniform magnetic field, to apply a per ...
2009Fixed bed reactor for solid phase surface derivatization of superparamagnetic nanoparticles
Heinrich Hofmann, Jatuporn Salaklang, Alke Fink, Benedikt Steitz, Andrija Finka
The functionalization of nanoparticles is conditio sine qua non in studies of specific interaction with a biological target. Often, their biological functionality is achieved by covalent binding of bioactive molecules on a preexisting single surface coatin ...
2007Neutral particle analyzer diagnostics on the TCV tokamak
Basil Duval, Alexander Karpushov, Christian Schlatter
Experimental apparatus and data analysis techniques used in neutral particle analyzer (NPA) diagnostics on the Tokamak a Configuration Variable (TCV) are described. Two NPAs are used on TCV to measure the energy spectrum of neutral particle fluxes from the ...
2006Magnetic Angular Encoder Using an Offset Compensation Technique
Quality and resolution of integrated microsystems using Hall sensors dedicated to an angular encoder are strongly dependent on the accuracy of the relative position of Hall sensors and on the offset of electronic front end circuitry. In this paper, we desc ...
Institute of Electrical and Electronics Engineers2004Analytical formula for rotating motor permanent magnet MMF in a general case
Yves Perriard, Marcel Jufer, Miroslav Markovic
This paper presents an analytical formula for the permanent magnet (PM) magnetomotive force (MMF) in a slotted PM rotating motor. To derive this formula, an analytical 2D solution of Poisson's equation for the equivalent slotless configuration using the Fo ...
