Surface Magnetism Field Surface magnetism refers to the magnetic induction intensity at a certain point on the surface of the magnet, and the unit is Gauss Gs or Tesla T (1T=10000Gs). The surface magnetism at different positions on the surface of the magnet is not the same. Generally speaking, "surface magnetism" refers to the center [...]
Magnetic Moment The generation of the magnetic field can be divided into two aspects: one is based on the moving current (electromagnetic induction), and the other is based on the spin of the basic particles of matter. The first is the magnetic effect of current that we are more familiar with, which is the magnetic [...]
Magnetic induction B and magnetic polarization J Practice and theory have proved that when a ferromagnetic or ferrimagnetic substance is magnetized in a magnetic field, in addition to the magnetic field in the substance, because the magnetic moments of the atoms of the ferromagnetic substance turn to the direction of the external magnetic field, it [...]
What is the MAGNETIC MOMENT The magnetic moments is a property that we use to verify the quality of our magnets. It is a way to measure the strength of a magnet and is widely used throughout the industry. Moreover, it is an easy, quick, and repeatable measurement. The magnet grade and magnet volume define [...]
How to Magnetize and Demagnetize a Permanent Magnet Magnets are items with poles and a magnetic field. This is due to the configuration of its electrons. There are three metals that are naturally magnetic; iron, nickel, and cobalt. These metals allow the electrons to configure in such a way that magnetic fields are created around [...]
Why can magnets absorb iron? Where does its energy come from? There is a magnetic field around the magnet. The magnetic field is a special kind of material. He stores the magnetic energy in the magnetic field. The magnet attracts iron because the iron also has small magnetic domains, which can be easily attracted by [...]
What use are magnets? Maybe you think magnets are interesting; maybe you think they're boring! What use are they, you might ask, apart from in childish magic tricks and scrapyards? You might be surprised just how many things around you work by magnetism or electromagnetism. Every electric appliance with an electric motor in it (everything [...]
Magnetism Electricity: Theory of Electromagnetism Electromagnets show that you can make magnetism using electricity. In fact, as European scientists discovered in the 19th century, electricity always makes magnetism when it moves about or changes. Every time an electric current flows in a wire, it generates a magnetic field all around it. Changing electricity, in short, [...]
SIX Things to Know About Magnets Almost everyone knows these six basic facts about how magnets behave: 1, A magnet has two ends called poles, one of which is called a north pole or north-seeking pole, while the other is called a south pole or south-seeking pole. 2, The north pole of one magnet attracts [...]
How does a tool magnetizer and demagnetizer work? These things (pictured below). I get how the magnetizer works: a permanent magnet magnetises the tool bit, but how is the magnetic fields arranged in the demagnetizer in order to demagnetize tools? These things are unpowered completely passive blocks, presumaly containing a magnet and some iron/steel parts. [...]
Nanoscale Dominoes: Magnetic Moments Topple Over in Rows, Magnetic Moments, magnetic switches, magnetic structure, magnetic information Physicists at the Institut für Festkörperforschung in Germany have discovered a type of domino effect in rows of individual manganese atoms on a nickel surface. They determined that the magnetic arrangement of these nanowires varies depending on their lengths. Using computer simulations and [...]
