Environmental magnetism — A personal perspective

Quaternary Science Reviews, 1991
Abstract Environmental magnetism is a versatile methodology applicable to a wide range of environmental studies and contexts. The complexity and unfamiliarity of many natural magnetic assemblages, coupled with the very versatility and sensitivity of the measurements can often limit interpretations at present, and there is an urgent need to improve ...

Environmental Applications of Magnetic Measurements

Science, 1980
A wide range of examples of the application of magnetic measurements to environmental studies illustrate the advantages of magnetic techniques over conventional methods. Magnetic measurements, in both the field and the laboratory, are particularly useful for reconnaissance work because of their speed and flexibility, Quantification as well as simple ...

Magnetic nanocomposites for environmental remediation

Advanced Powder Technology, 2013
This article provides an overview of current research activities on the synthesis and applications of magnetic nanocomposites, especially highlights their potential environmental remediations such as heavy metal (Cr, As, Pd, Hg) removal. After a brief introduction of the emergency situation of heavy metal pollution all over the world and current ...

Quieting an environmental magnetic field without shielding

Review of Scientific Instruments, 2020
We construct an active magnetic compensation device and propose an efficient magnetic compensation method that suppresses a wider range of frequencies and amplitudes of time-varying magnetic fields than conventional methods. This system can compensate for all frequencies in the bandwidth of the sensors used by analyzing and extracting the spectral ...

Are environmental magnetic fields dangerous?

Physics World, 1992
In the general environment, at home and in the factory or office, people are exposed to electromagnetic radiation from computers, domestic appliances, power transmission lines and manufacturing tools and products. It is often thought that the electromagnetic fields associated with these may have adverse effects, and indeed court cases have sometimes ...
