  • Magnet Common Sense

Magnet Common Sense

Magnet Common Sense As we all know, magnets are very useful in our daily life. To let those who are new to the world of magnets have a better understanding of them, in this article, we’ll introduce some common sense of magnets. A Brief History of Magnets The ancient Greeks and Chinese discovered a naturally [...]

  • Ferrite Magnets Replace Rare-earths in EV Motor

Ferrite Magnets Replace Rare-earths in EV Motor

Ferrite Magnets Replace Rare-earths in EV Motor Yaskawa says it has developed an electric vehicle (EV) motor that avoids the need for neodymium magnets, using much cheaper and easier-to-obtain ferrite magnets instead. The development is intended to reduce the company’s dependence on rare-earth materials, such as neodymium and dysprosium, whose prices have fluctuated widely in [...]

  • Superconducting Magnet Construction

Superconducting Magnet Construction

Superconducting Magnet Construction A superconducting magnet is an electromagnet made from coils of superconducting wire. They must be cooled to cryogenic temperatures during operation. In its superconducting state the wire has no electrical resistance and therefore can conduct much larger electric currents than ordinary wire, creating intense magnetic fields. Superconducting magnets can produce greater magnetic [...]

How does Magnetism Affect a Watch?

How does Magnetism Affect a Watch? Watches can be adversely affected by magnetism and may gain or lose time. It is important not to leave a watch close to magnetic objects for a long periods. In particular, cell phones, television and PC speakers, magnetic necklaces, handbag clasps, hair-driers, electric razors, magnetic parts of refrigerators are [...]

  • Watch Movement Rotor Magnet

Watch Movement Rotor Magnet

Watch Movement Rotor Magnet Different historical periods have their timer utility. The earliest astronomy timing was taken advantage of the sun or the moon to time, and then fluid is also utilized to time. As a modern invention, quartz watch has many merits, include the simple structure, easy to assemble, strong endurance, shockproof, accurate timepieces, [...]

  • plastic injection molded permanent magnet for electronic expansion valve

Permanent Magnet for Electronic Expansion Valve (EEV)

Permanent Magnet for Electronic Expansion Valve (EEV) electronic expansion valves are designed for use in air conditioning and refrigeration systems or in heat pumps. The valve controls the automatic adjustment of refrigerant flow rate and makes the system work under optimized conditions for the purpose of fast cooling or heating, precise temperature control and energy [...]

  • Magnetization Dynamics

Magnetization Dynamics

Magnetization Dynamics 1 Introduction Magnetization dynamics, where one investigates the time-dependent motion of the magnetization rather than its equilibrium behavior, are fundamental to the properties of magnetic materials. It is worthwhile remembering that the concept of spin waves was introduced by Bloch  in 1930 in order to calculate the magnetic contribution to the specific heat [...]

The Basics of Magnetism

The Basics of Magnetism To understand what makes a material magnetic, you have to think small. Really small. Like atom small. Atoms are the basic building blocks that come together to form molecules, which come together for form, well, just about everything around you! Inside every atom there are protons, neutrons, and electrons. Protons have [...]

MPCO Can Test the Angular Direction (ϕ, θ) of Magnetization!

MPCO Can Test the Angular Direction (ϕ, θ) of Magnetization! How well do you need to know your magnets? Using our m-axis testing equipment, magnetic moment, remanence and magnetization direction of magnetic dipoles can be characterized with high precision. The calculation is based on determination of the dipole using an integrated AMR sensor set-up. The [...]

Magnetic Applications Package Closure Magnets

Magnetic Applications Package Closure Magnets Design Considerations In addition to your physical and design aesthetic requirements, we'll want to know the closure retention force in order to determine whether two magnets or one magnet with a steel disc or strike plate should be used. Air Gap (the space between the magnets or steel receptive piece) [...]

  • B-H Curve for Permanent Magnets

B-H Curve for Permanent Magnets

B-H Curve for Permanent Magnets What is a B-H curve first of all? B is the nomenclature for magnetic flux density (induction) and H is magnetic field strength; a B-H curve plots out the relationship between them for a particular ferromagnetic material. The changes in magnetic flux density is dependent on the magnetic field strength. [...]
