Manufacturing methods and magnetic characteristics of magnetic wood

Journal of Magnetism and Magnetic Materials, 2004
The relationship between wood construction and DC magnetic characteristics for three types of magnetic wood was experimentally investigated. The results show that the magnetic characteristics of each type of magnetic wood are dependent on the magnetic materials, the density of the magnetic material and the construction of the wood.

Heating characteristics of magnetic wood by induction heating

IEEE Transactions on Magnetics, 1999
The purpose of this article is to examine the possibility of using magnetic wood as a heating board. This article covers top and side surfaces of heating characteristics for three types of magnetic wood (impregnated, powder and coating types) when using three different excitation coil types (solenoid, meander and spiral coil).

Experimental study on magnetic and heating characteristics of magnetic wood

Journal of Applied Physics, 1999
Magnetic wood, wood which demonstrates magnetic characteristics, was introduced by the Oka group in 1991. Based on previous studies, we have proposed that magnetic wood can be used as a heating board by induction heating, applying a high frequency magnetic field.

Nuclear magnetic resonance imaging of waterlogged wood

Studies in Conservation, 1995
Abstract The authors evaluate the usefulness of nuclear magnetic resonance (NMR) imaging to conservation research, and assess the ability of the technique to obtain non-destructive images from waterlogged wood samples, both prior to conservation and during consolidation. In the absence of iron salts, very high-quality images of internal wood structures,

Magnetic Resonance Studies of Thermally Modified Wood

Holzforschung, 2002
Summary Thermal modification of wood produces a wood material with many interesting properties, such as enhanced dimensional stability, lower equilibrium moisture content and increased biological durability. Changes in the chemical structure of pine (Pinus sylvestris) caused by thermal treatment were investigated by studying various ...

Magnetic Resonance Studies of Wood Log-Drying Processes

Forest Products Journal, 2017
Abstract Spatially resolved measurements of moisture content (MC) in black spruce (Picea mariana Mill.) logs were undertaken by unilateral magnetic resonance (UMR) and magnetic resonance imaging (MRI). The goal of this study was to understand drying behaviors of the different regions in black spruce wood logs.

Humidity effect for the magnetic woody characteristics of powder type magnetic wood

Digest of INTERMAG 2003. International Magnetics Conference (Cat. No.03CH37401), 2004
In this paper, we focused on the relationship between humidity and magnetic characteristics of powder type magnetic wood. The magnetic powder ratio, wood powder density and magnetic binder density were all examined as parameters for AC permeability /spl mu//sub iac/. The experimental results demonstrated the humidity effect for magnetic characteristics

Lightweight and Construable Magnetic Wood for Electromagnetic Interference Shielding

Advanced Engineering Materials, 2020
Currently, due to the rapid development of communication technology, electromagnetic interference (EMI) and irradiation have become an emerging environmental pollutant. Herein, hierarchical and porous structured wood is used as the lightweight three‐dimensional organic scaffold for the incorporation of magnetic iron oxide nanoparticles through an in ...

Wood ants orient to magnetic fields

Proceedings of the Royal Society of London. Series B: Biological Sciences, 1995
We report here, the first evidence that ants Formica rufa L. exhibit a magnetic compass response. For a period of seven days, foragers were trained to visit a food source accessed through a choice chamber situated inside a solenoid. When all other orientational cues were eliminated, the distribution of ants entering the choice chamber was significantly

Transparent magnetic wood composites based on immobilizing Fe3O4 nanoparticles into a delignified wood template

Journal of Materials Science, 2016
Wood is one of the key renewable resources due to its excellent structure and physical properties. Functionalized wood and wood-based materials not only possess important engineering applications but also great potential in some new technology fields, such as electronics, optics, and energy.
