Ring magnets are versatile and can be used in a variety of applications, including scientific experiments, medical equipment, and manufacturing. They are shaped like a ring with a hole in the center and have north and south poles that can be segmented in different ways around the ring. The unique polarization of ring magnets allows [...]
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 [...]
Manufacturing Processes for Permanent Magnets: Bonding and Emerging Methods Abstract Permanent magnets produce magnetic fields and maintain the field even in the presence of an opposing magnetic field. They are widely used in electric machines, electronics, and medical devices. Part I reviews the conventional manufacturing processes for commercial magnets, including Nd-Fe-B, Sm-Co, alnico, and ferrite [...]
Soft Ferrites Applications Ferrites are polycrystalline oxides manufactured by ceramic technology and belong to a class of materials that exhibit the technically useful property of ferromagnetism. In a ferromagnetic material, magnetism occurs under the influence of an externally applied field. On removals of this field, material returns to its non-magnetic state. This behaviour is termed [...]
About LLC Converter Topology Power conversion is the process of converting electrical energy from one form to the other. The devices responsible for this conversion can work to convert alternating current (AC) into direct current (DC) & vice versa. They range from simple setups like a transformer to more complex conversion systems like resonant converters. [...]
Why are Ferrite Cores Used for Antenna Coils? Antennas have been used for many years to catch waves that are invisible to the naked eye. These electromagnetic waves travel around us, carrying information that’s grabbed by the antennas & used by the application it's attached to. Since all current-carrying wires around us develop their own [...]
Know About Ferrite Cable Cores As long as electronic items surround us, electromagnetic waves will be around us too. These waves are naked to the human eye and won’t affect your day-to-day activities. Born from the flow of electric current, these, however, can affect parts of devices like the power supply cable. The cable acts [...]
Know About Ferrite Core Transformers A transformer is a device used in the distribution and transmission of alternating current (AC). It does so by stepping up (increasing) or stepping down (decreasing) the voltage to attain the desired values. Hence, in simple terms, you can understand it as a voltage control device that works on the [...]
Know About Coated & Uncoated Toroidal Cores Toroidal cores are used as power shapes in electric circuits such as inductors and transformers. They are an ideal material to use at low frequencies where large inductances are required. The cores offer the advantage of material permeability and have a uniform cross-sectional area. They do not have [...]
