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? 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 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 Molding Magnet Component in Electronic Expansion Valve for Air-condition, Plastic Injection Bonded Neodymium Magnet for Electronic Expansion Valve Key Specifications/Special Features: Magnet materials: NdFeB Plastic resin: PPS Second injection over-molding with the polymers (PPS/PA) Magnetizing pattern: multi-pole radial magnetization Simultaneous incorporating insert Available for electronic expansion valve of air-condition We are a well-reputed [...]
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 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 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! 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 [...]
Magnets For Guitar Pickups One of MPCO favorite applications is magnets for pickups. There are many things to consider if you are looking to optimize your guitar to its full potential, and pickups are arguably one of the most important elements of customization. If you are a skilled designer of pickups looking to create the [...]
Adhesive Backing Magnetic Discs The self-adhesive backing on the magnets means they can be fixed almost anywhere, in place under card flaps, on the back of signs or used in packaging. Also used with gift boxes, name badges and greetings cards that can stick to a refrigerator. If you haven't used magnetic closer discs before, [...]
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) [...]
Hall Effect Sensor Magnets Let MPCO help choose the magnet to best suit your specific sensor application requirements. We have experience designing around the effect of environmental conditions, temperature, shock, vibration, corrosion resistance, magnetic stability, manufacturability, form factor (and more!) related to the use of magnets with sensors and can help optimize the performance of [...]
