Iron filings on a magnet. Iron filings are very small pieces of iron that look like a powder with a dark-grey appearance. [1] As the name suggests, iron filings can be obtained from metal working operations as the scrap material filed off larger iron and steel parts. [2]
Combined with certain metallic species, amorphous films can crystallize in a process known as metal-induced crystallization (MIC). The effect was discovered in 1969, when amorphous germanium (a-Ge) films crystallized at surprisingly low temperatures when in contact with Al, Ag, Cu, or Sn. [1]
Crystallization is the process by which solids form, where the atoms or molecules are highly organized into a structure known as a crystal.Some ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.
There remain a few ambiguities about the effect. The current theory of triboluminescence—based upon crystallographic, spectroscopic, and other experimental evidence—is that upon fracture of asymmetrical materials, charge is separated. When the charges recombine, the electrical discharge ionizes the surrounding air, causing a flash of light.

If a charge is lowered into the innermost pail, an exactly equal induced charge will appear on the outside of the outer pail. The charge on the outside of each pail induces an equal charge on the next. If one of the pails is grounded, the charge on all the pails outside goes to zero.
