    How Magnets Work HowStuffWorks

    Apr 02 2007 Iron for example has four unpaired electrons with the same spin. Because they have no opposing fields to cancel their effects these electrons have an orbital magnetic moment. The magnetic moment is a vector-- it has a magnitude and a direction. Its related to both the magnetic field strength and the torque that the field exerts.

    What is Moving Iron or MI Instrument Definition

    Definition The instrument in which the moving iron is used for measuring the flow of current or voltage is known as the moving iron instrument. It works on the principle that the iron place near the magnet attracts towards it. The force of attraction depends on the strength of the magnet field.The magnetic field induces by the electromagnet whose strength depends on the magnitude of the.

    MAGNETIC SEPARATIONPRINCIPLES AND APPLICATION IN

    Magnetic Separation is one of the physical concentration processes that utilizes the differences in magnetic properties of various minerals present in the ore body. The magnetic fraction may be valuable or gangue depending upon its end use in a particular process and so also the non-magnetic fraction e.g. separation of magnetite magnetic from quartz non-magnetic separation of tin.

    Dec 22 2009 The iron carbide Fe 7 C 3 exhibits two types of basic crystal structures an orthorhombic o form and a hexagonal h one. First-principles calculations have been performed for the basic Fe 7 C 3 forms and for the related -Fe 3 C cementite phase. Accurate total-energy calculations show that the stability of Fe 7 C 3 is comparable to that of -Fe 3 C.The o-Fe 7 C 3 phase is more.
