The separation process in which the materials susceptible to magnet are separated from a mixture by magnetic driving force is known as magnetic separation. This method takes the advantage of the difference in the magnetic principles of the minerals (ferromagnetic, paramagnetic or diamagnetic). A journal is a periodical publication intended to further progress of science, usually by reporting new research. Most journals are highly specialized, although some of the oldest journals publish articles, reviews, editorials, short communications, letters, and scientific papers across a wide range of scientific fields. Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. Each such journal article becomes part of the permanent scientific record.
