Alnico: The “Magic Magnetic Core” of High – end Speakers

In the high-end audio field, the Alnico magnet is truly the “magic magnetic core” and highly prized. Back in the early 20th century when audio emerged and the first commercial vacuum tube radios came out, the Alnico magnet brought speakers to life. Speakers using it then had an average lifespan about 35% longer than those […]

Alnico Magnets: Unlocking the Magic Code of Teaching Magnetic Fields

Among a vast array of magnetic materials, alnico magnets emerge as the top choice. So, what exactly makes them so highly favored? 1. Super – Strong Magnetism, Exhibiting Potency Alnico magnets possess a high residual magnetism, which empowers them to […]

How to manufacture laminated magnets:

The following are the general steps for manufacturing laminated magnets: Material Preparation   Thin Sheets of Magnetic Materials Select appropriate magnetic materials, such as neodymium iron boron (NdFeB), ferrite, etc. The thickness of these thin sheets usually ranges from 0.1 to 1 mm, depending on the application requirements. For example, in high-frequency application scenarios, thinner […]

What are the advantages of laminated magnetic steel

Reduce Eddy Current Losses In an alternating magnetic field, an induced electromotive force will be generated inside the bulk magnetic steel, which then forms eddy currents, resulting in energy losses and heat generation. However, laminated magnetic steel is composed of thin magnetic steel sheets stacked one on top of another. Since the sheets are insulated […]

Alnico: The Ideal Choice for Milestone Motorcycle Accessories

Among the numerous components of motorcycles, the accuracy and stability of the odometer parts are of vital importance. Due to its unique material properties, aluminum-nickel-cobalt (AlNiCo) has become the preferred choice for motorcycle odometer parts. In terms of magnetic strength and stability, AlNiCo permanent magnetic materials have significant advantages. Their relatively high residual magnetic flux […]

The relationship between motor magnet size and motor power

There is a certain relationship between the size of the motor magnet and the motor power, especially in the design of permanent magnet synchronous motor (PMSM) and brushless DC motor (BLDC), the size, shape and magnetic properties of the magnet directly affect the motor output power, efficiency and volume. Specifically, the relationship between the size […]

Why are multi-pole magnetized rings a natural Halbach array?

Multi-pole magnetic rings are called “natural Halbach arrays” because they are very similar in design and function to the principles of the Halbach Array. Here are the specific reasons: 1. The principles of magnetic field enhancement and weakening are the same The Halbach Array is a specially arranged magnet array, which is characterized by enhancing […]

Why SmCo magnets are used in SMT fixtures

The following are the main reasons why SmCo magnets are used in SMT fixtures:   Firstly, SmCo magnets have a high magnetic energy product, which means that they can generate a relatively strong magnetic field in a relatively small volume. In SMT fixtures where certain requirements are placed on the spatial layout, a compact and […]
