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] They are very often used in science demonstrations to show the direction of a magnetic field. Since iron is a ferromagnetic material, a magnetic field induces each particle to become a tiny bar magnet ...
Iron filings used to show the magnetic field lines of a bar magnet. In the history of physics , the concept of fields had its origins in the 18th century in a mathematical formulation of Newton's law of universal gravitation , but it was seen as deficient as it implied action at a distance .
Recycling centres use magnetic separation often to separate components from recycling, isolate metals, and purify ores. [1] Overhead magnets, magnetic pulleys, and the magnetic drums were the methods used in the recycling industry. [1] Magnetic separation is also useful in mining iron as it is attracted to a magnet.

A magnetic field (sometimes called B-field [1]) is a physical field that describes the magnetic influence on moving electric charges, electric currents, [2]: ch1 [3] and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.
Chilling video footage obtained by The Post shows the cowardly brute roaming the edge of the platform while the victim appears to be looking at his phone as the train pulls into the station.
Craigslist is great for many things — finding your next couch, buying a pair of roller skates, or maybe even finding an apartment. But it shouldn't really be a place to find your next pet. There ...
