The Power of Attraction: Magnets in Particle Accelerators In 1820, Hans Christian Oersted gave a demonstration on electricity to a class of advanced students at the University of Copenhagen in Denmark. Using an early battery prototype, he looked to see what effect an electric current would have on a compass, and since he hadn’t had [...]
Alnico Magnets are Used for Particle Accelerators Accelerating Science: Alnico in Particle Accelerators In the cutting-edge world of particle physics, Alnico magnets play a crucial role in steering and focusing beams of charged particles within accelerators. These facilities, such as the Large Hadron Collider (LHC), investigate the fundamental components of matter and the forces that [...]
Alnico Magnets are Used for Electric Guitars In the vast universe of magnetism, Alnico magnets stand out for their remarkable properties and versatile applications. Comprised of aluminum (Al), nickel (Ni), cobalt (Co), and often including iron and other metals, Alnico magnets were developed in the 1930s and have since been integral to a myriad of [...]
Alnico vs. Rare Earth Magnets What is the difference between alnico and rare earth magnets? In the vast and evolving world of magnetics, Alnico and rare earth magnets stand out due to their distinct properties and wide range of applications. From basic science projects to complex industrial machinery, understanding the differences between these two types [...]
Thermal Stability of Anisotropic Bonded Magnets Prepared by Additive Manufacturing Abstract In this research, anisotropic NdFeB + SmFeN hybrid and NdFeB bonded magnets are additively printed in a polyphenylene sulfide (PPS) polymer binder. Printed NdFeB + SmFeN PPS bonded magnets displayed excellent magnetic properties (Br [remanence] = 6.9 kG [0.69 T], Hcj [coercivity] = 8.3 [...]
New Measurement Technique Characterizes Permanent Magnets Permanent magnets are widely used for sensor and motor applications. Besides these, magnetic fields are also used for applications such as storage of information and fraud protection on documents. With the number of critical applications continuing to rise, developers and producers are increasingly forced to meet safety requirements, as [...]
Permanent Magnets in a Changing World Market There are several commercially available permanent magnets. In sequence of invention they are: alnico, ferrite, SmCo (samarium cobalt), NdFeB (neodymium iron boron, Neo), and SmFeN (samarium iron nitride). The last three types are considered “rare earth” magnets because they contain one or more rare earth elements. In terms [...]
Magnetic Materials in Loudspeakers (Horns) The core component responsible for producing sound in audio equipment is the loudspeaker, commonly known as the horn, whether it is a stereo or a headset, this key component is indispensable. The loudspeaker is a transducer device that converts electrical signals into acoustic signals. The performance of the loudspeaker has [...]
Determining Factors that Affect Magnetic Field Strength Consider a magnet's characteristics. Magnetic properties are described using these characteristics: Coercive magnetic field strength, abbreviated Hc. This represents the point at which the magnet can be demagnetized (degaussed) by another magnetic field. The higher this number, the more difficult it is to degauss the magnet. Residual magnetic [...]
Types of Magnets Magnets are common in normal life, and almost everyone knows about them. In particular, magnets are known as those materials that have the property of attracting and repelling certain metal materials, such as iron and nickel. However, this is not always the case. Magnets can sometimes lose their magnetic property and thus [...]
Cylindrical Permanent Magnetic Assemblies MPCO offers a wide variety of cylindrical permanent magnetic assemblies. Our assemblies come in alnico, ceramic, magnets with thru-holes, magnets with bolts and loops, and retaining magnets. Alnico magnets are ideal for high heat applications and Ceramic magnet assemblies are the most economical typically. Alnico refers to a type of iron [...]
