The Science of Magnetic Field Lines

Alternatives to iron filings include steel BB pellets, tin-plated iron filings (which won't rust), small paper clips, staples, or magnetite sand. The advantage to using particles of iron, steel, or magnetite is that the particles form a detailed map of magnetic field lines. The map also gives a rough indication of magnetic …

Magnetite biomineralization in the human brain.

Aug 15, 1992· Magnetic property data indicate the crystals are in clumps of between 50 and 100 particles. Biogenic magnetite in the human brain may account for high-field saturation effects observed in the T1 and T2 values of magnetic resonance imaging and, perhaps, for a variety of biological effects of low-frequency magnetic fields.
