U-shaped horseshoe ferrite magnets are classic U-shaped special-shaped permanent magnets made of high-quality ferrite magnetic materials, also known as horseshoe magnets. The product presents a U-shaped integral structure, with two parallel magnetic poles at the upper end and an integrated connecting base at the bottom, forming a natural closed magnetic circuit structure. As a traditional and mature magnetic product, U-shaped horseshoe ferrite magnets have the characteristics of low cost, stable magnetic performance, strong anti-demagnetization ability, good temperature resistance and long service life. They are widely used in teaching experiments, industrial adsorption, mechanical equipment, electrical appliances and daily supporting fields, and are one of the most cost-effective permanent magnet products.

The production process of U-shaped horseshoe ferrite magnets adopts dry pressing sintering integrated molding technology. The production steps include ferrite raw material batching, high-pressure mold pressing, high-temperature sintering, integral grinding, edge chamfering and directional magnetization. The product is integrally formed by mold pressing, with standard U-shaped structure, uniform pole spacing on both sides, stable overall structure and no easy deformation. After high-temperature sintering, the internal crystal structure of ferrite is stable, with excellent magnetic stability and anti-aging performance. Different from NdFeB magnets, ferrite materials have strong anti-demagnetization ability, will not produce spontaneous demagnetization in natural environment and conventional industrial environment, and have extremely long service life. The surface of the product is smooth and flat after fine grinding, with uniform magnetic force on the two poles, and the magnetic field distribution is regular and stable.

U-shaped horseshoe ferrite magnets have outstanding structural and performance advantages. Firstly, the U-shaped horseshoe structure concentrates the magnetic poles on the two parallel ends, which effectively gathers the magnetic field force, avoids the dispersion of magnetic force, and makes the adsorption force more concentrated and powerful; secondly, the integral connecting base structure improves the overall structural stability of the magnet, with strong compression resistance and falling resistance, and is not easy to break and damage in the process of use; in addition, ferrite materials have excellent temperature resistance, can work stably in the temperature range of -40℃ to 120℃, and will not be affected by ambient temperature to produce magnetic attenuation; most importantly, the product has ultra-high cost performance, low production cost, stable batch quality, and is suitable for large-scale popular use.

The application fields of U-shaped horseshoe ferrite magnets cover teaching and scientific research, industrial adsorption fixing, electrical equipment, toy manufacturing, and hardware auxiliary accessories. In the field of teaching and scientific research, it is the most commonly used experimental magnet for primary and secondary school physics magnet teaching, used for demonstrating magnetic field distribution, magnetic attraction and repulsion principles, and electromagnetic induction experiments, with intuitive teaching effect and stable performance; in industrial production, it is used for simple iron workpiece adsorption, mechanical equipment auxiliary positioning, and electrical circuit magnetic induction components; in the toy industry, it is applied to magnetic toy accessories, educational puzzle toys, and children's science popularization toys, with safe and stable magnetic performance; in daily hardware, it is used for magnetic adsorption fixing of household appliances, tool magnetic fixing and simple magnetic limit components.

U-shaped horseshoe ferrite magnets support the customization of different sizes, pole spacing and magnetic strength. Conventional standard models are in stock in large quantities, which can meet the conventional use needs of customers; special large-size and small-size U-shaped magnets can be customized according to demand. The product has the characteristics of stable magnetism, strong durability, low price, wide adaptability and no easy demagnetization. Although the magnetic strength is lower than that of NdFeB magnets, it has irreplaceable advantages in cost performance and long-term stability. It is a classic and practical permanent magnet product, which has been widely used in various basic industrial fields, teaching fields and daily supporting fields, and has stable market demand for a long time.
