What is the MAGNETIC MOMENT

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

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?

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?

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

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

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?

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

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 [...]
