Magnetic 3D Mapping System HS Magnetics utilizes various custom designed testing machines for magnetic measurements. Below are two magnetic mapping systems outlined with descriptions as a combination of our engineering solutions. Magnetic field mappers measures the field magnitude and direction over a predetermined range of positions. These measurements are made by accurately positioning a collection [...]
Permanent Magnets in Electric Vehicles, Permanent Magnetics in Electric Vehicles EV Motors and permanent magnets Rare-Earth magnets are higher in cost than copper windings, making the option of using a magnet-less AC induction or brushed DC motor attractive. Many applications (vacuum cleaners, mixers, hair dryers, most home fans, etc) will opt for the less expensive [...]
How strong is a 12000 Gauss magnet? Long answer: 12000 gauss = 1.2 tesla. If that’s a rare earth magnet, NdFeB, it’s about an N35. State of the art 15 years ago but now N48 is the garden variety and you can pay a little more and get up to N56 in quantity. B field [...]
Understanding Magnet Grades and Magnet Tables Each day we get asked questions about the differences in magnetic materials. Neodymium Magnets, Samarium Cobalt (SmCo) Magnets, Ceramic Magnets, Alnico Magnets, Bonded Magnets, and Injection Molded Magnets all have various options, and choosing the correct grade for your application is critical. This article will try to simplify how [...]
Tiny NdFeB Magnets in Smartphones and Personal Electronics Small Tiny NdFeB Magnets in Smartphones Neodymium (NdFeB) magnets are an invisible part of every smart phone. These tiny magnets are critical to the function of the phone, working quietly behind the scenes inside the phone case. These internal magnets are typically used in the speaker, receiver, [...]
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 [...]
Factors Affecting Magnetic Force of Permanent Magnets Many customers who came to inquire about the magnet’s attraction asked the most about how many Gauss can attract, or send a specification to ask how much it can attract. This is introduced in previous articles. If you are interested, you can click to understand. Today’s main Let’s [...]
HSMAG Supply Custom Neodymium Magnet Service The custom neodymium magnet is a very small market in the magnet business，so customer is hard to find a company whom can offer them good custom magnet service. In the magnet business, most of the customer just buy the normal magnet. Most of the time, that is big size [...]
How Does Heat Affect Neodymium Magnets? A key property for stable magnet materials is to keep all of its domain atoms rotate in the same direction. When the magnets are exposed to heat, the balance between temperature and magnet atoms are disturbed affecting their magnetic properties. In other words, the tiny magnetic atoms act like [...]
Samarium Cobalt MATERIAL GRADES Known as Rare Earth magnets, Samarium Cobalt (SmCo) are alloys of the Lanthanide group of elements. SmCo magnets have been commercially available since the early 1970’s, first as a 1-5 Type alloy, and later with the introduction of the 2-17 type. Both alloys offer outstanding thermal stability and excellent corrosion resistance. [...]
How to Judge the Quality of Sintered NdFeB Magnets? Sintered NdFeB permanent magnets, as one of the important substances to promote contemporary technology and social progress, are widely used in the following fields: computer hard disk, magnetic resonance imaging, electric vehicles, wind power, industrial permanent magnet motors, consumer electronics (CD, DVD, mobile phones, stereos, copiers, [...]
