Micro Reciprocating Actuator Using Magnetic Fluid and Two Permanent Magnets

Permanent magnets and hard magnetic materials

This review deals with the definition and development of hard magnetic materials with special emphasis on more recent developments in this field. After discussing the fundamental properties of all hard magnetic materials, based on the intrinsic and extrinsic properties, some remarks on the history of hard magnetic materials and permanent magnets are given. The important hard ferrites are only b...

Study of a Mini-Actuator with Permanent Magnets

The paper presents an analytical method for the determination of the magnetic force produced by a mini – actuator with permanent magnets. The results are compared with those obtained by performing a numerical field analysis with COMSOL Multiphysics, showing a very good agreement. The study reveals that the actuator has two equilibrium points, one of which is stable and the other one unstable.

Fabricating Unidirectional Magnetic Papers Using Permanent Magnets to Align Magnetic Nanoparticle Covered Natural Cellulose Fibers

This paper reports a simple innovative method to align magnetic cellulose fibers by using a simple permanent magnet to fabricate unidirectional magnetic papers. Magnetic cellulose fibers were made by in situ synthesis of magnetite nanoparticles on alpha cellulose pulp extracted from American southern pine. Scanning electron microscope micrographs and energy dispersive X-ray spectroscopy maps in...
