Magnetite forming in iron pipes - MERUSONLINE

Magnetite, with chemical formula: Fe3O4, is an iron ore found in igneous, metamorphic rocks. It belongs in the same group of iron ore as the hematite or the maghemite. Magnetite is a chemical compound of iron and oxygen and therefore an oxide. Magnetite is physically rather stable, as it is an octahedral crystal.

magnetic fields - Why is a steel ball-bearing repelled ...

$begingroup$ Thanks for your answer, which is a bit beyond my present abilities to understand fully. I thought that by Maxwell's 2nd equation that ∇⋅B = 0. i.e., the divergence of a magnetic field is zero. So, all of the magnetic force being emitted from the permanent magnet is cancelled out when that same force returns to the other pole of the magnet.
