    Basics of Magnetism by Ron Kurtus (revised 29 January 2013) Magnetism is a force of attraction or replusion that acts at a distance. It is due to a magnetic field‚ which is caused by moving electrically charged particles. It is also inherent in magnetic objects such as a magnet. A magnet is an object that exhibits a strong magnetic field and will attract materials like iron to it. Magnets have two poles‚ called the north (N) and south (S) poles. Two magnets will be attacted by their opposite poles

    the outer core fluid is not fully understood. Some researchers have linked rotation of Earth‚ due to "original spin" at the time our solar system formed‚ to the rotation of the outer core. Circulating magma in the molten outer core generates a weak magnetic field‚ which the researchers suspect may be leaking into the inner core and generating an electric current. The twisting force generated by this electromagnetic interaction may be what drives the inner core’s rotation.” Third‚ the Marianas Trench

    Some materials have a feature known as ferromagnetism. The prefix "ferro" refers to Iron‚ which is one such material. Ferromagnetic materials have the ability to "remember" the magnetic fields they have been subjected to. An atom consists of a number of negatively charged electrons‚ orbiting around a positively charged nucleus. These electrons also possess a quantity known as spin‚ which is roughly analogous to a spinning top. The combination of orbital and spin motions is called the angular momentum
