Water Anti-scale Magnetic Treatment

Water Anti-scale Magnetic Treatment, Magnetic Water  Treatment Magnetic water treatment (also known as anti-scale magnetic treatment or AMT) is a method of supposedly reducing the effects of hard water by passing it through a magnetic field as a non-chemical alternative to water softening. Magnetic water treatment is regarded as unproven and unscientific. There is a lack [...]

Explaining Magnetism

Explaining Magnetism with The Domain Theory In the early 20th century, before scientists properly understood the structure of atoms and how they work, they came up with an easy-to-understand idea called the domain theory to explain magnetism. A few years later, when they understood atoms better, they found the domain theory still worked but could [...]

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 [...]

Magnetism

Magnetism Science is our understanding of how the world works—and generally the world works fine whether we understand it or not. Take magnetism, for example. People have known about magnets for thousands of years and they've been using them practically, as compasses, for almost as long. The ancient Greeks and Romans knew as well as [...]

Do magnets temperature affect magnetism in a magnet?

Do magnets temperature affect magnetism in a magnet? Yes, temperature affects the strength of a magnet. Colder temperatures will permit the magnetic field strength to increase a bit and hotter temperatures will decrease it a bit. The effects can be demonstrated by a simple experiment with a bar magnet and a handful of carpet tacks. [...]

Magnetic Halbach Arrays

Magnetic Halbach Arrays - MAGNETIC-BEARINGS & HALBACH ARRAYS A Halbach array is a special arrangement of magnets that 'directs' the magnetic field to allow high magnetism in particular locations and low magnetism in other locations. Magnetic Halbach Arrays There are a number of different assemblies and arrangements available. We can supply Halbach arrays [...]

Magnetic Measurements

Magnetic Measurements For measuring of the fundamental magnetic properties of a material (Br, bHc, iHc, BHmax, demagnetisation curve), Hysteresisgraph or BH-tracker is used. A BH-tracker consists of an iron (usually FeCo) yoke to form a closed circuit, electromagnets to create the demagnetizing field and fluxmeters to determine the demagnetizing field and the materials response. [...]

What is L/D ratio

What is L/D ratio L/D is a ratio to analyze the shape of a magnet, and it is a very important parameter to judge the temperature resistance ability of the magnet basically. MAGNET LD ratio Normally, we advise L/D ratio>0.5 (≥0.7 will be even better ) L/D ratio was calculated as follow: (1) [...]

How does a magnetic base work?

How does a magnetic base work? Magnetic bases can be one of two varieties: those with lever switches and those with push buttons Although the ON/OFF for the magnet may vary, the way the system works is still the same. The magnetic base is made up of four parts: one part non-ferrous metal spacer (metal [...]

How to avoid demagnetising magnet ?

Avoid Demagnetising Magnet Demagnetisation is the process whereby a magnet loses all of its magnetic properties. The magnet most prone to demagnetisation is the ferrite magnet due to the alloy it is made of, however all magnets can be demagnetised.
