  • How Are Ferrite Magnets Made

How Are Ferrite Magnets Made

How Are Ferrite Magnets Made? Ferrite magnet, also know as a ceramic magnet, is a kind of permanent magnet. Compared with other permanent magnets, ferrite magnets are hard and brittle and have lower magnetic energy. But it is not easy to demagnetize, not easy to be corroded, and low in price. Therefore, ferrite magnets are [...]

  • How Are Alnico Magnets Made

How Are Alnico Magnets Made?

How Are Alnico Magnets Made? Alnico magnet was successfully developed in the 1930s. It is composed of aluminum, nickel, cobalt, iron, and other trace metal elements. Thanks to their high coercivity and high Curie temperature, Alnico magnets are widely used in many industrial and consumer products, such as motors, electric guitar pickups, microphones, sensors, speakers, [...]

  • 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 [...]

  • 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 [...]

  • 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 [...]
