Abstract
Magnetic particulates in the environment, collected from surfaces and directly from the atmosphere, are reported. A significant percentage of magnetic material in many air‐borne samples consists of spherical magnetite from coal‐burning utilities and from iron/steel manufacturing with particle diameters 2–10 μm which correspond to average coercive fields of ∼100 Oe and remanence to saturation ratios of ∼0.1. The amount of air‐borne magnetic material that settles to the ground varies inversely with distance from its source.This publication has 14 references indexed in Scilit:
