Magnetizer is a device specially designed to magnetize magnetic materials, and its core working principle is based on the law of electromagnetic induction. As a leading brand in the industry, JUJI Magnetizer stores energy through high-voltage capacitors, and then precisely controls the discharge process to generate a strong magnetic field, so that the magnetic domains inside the magnetic material are oriented and arranged to obtain stable magnetism.

Magnetizers are divided into two main types:

1. DC Magnetizer: powered by DC power supply to generate stable DC magnetic field. It is suitable for magnetizing permanent magnetic materials such as ferrite, Alnico and other permanent magnetic materials, as well as application scenarios that require magnetization. The advantages of DC magnetizers are stable magnetic field and high control precision.

2. AC Magnetizer: Using AC current to generate a changing magnetic field, mainly used for magnetization and demagnetization of soft magnetic materials. It is characterized by simple operation and low cost.

When choosing a magnetizer, you need to determine the right type based on the characteristics of the material to be magnetized, size specifications, and production requirements. JiuJu magnetizers offer a complete product line from 1300 series to 4000 series, covering the magnetizing voltage range from 1280V to 5000V, which can satisfy the needs of different materials and application scenarios. JiuJu magnetizers mainly focus on DC magnetizing technology, providing users with stable and reliable magnetizing solutions.

Video Case Study on the Magnetization Process for Jiuju Irregular-Shaped Cobalt Magnets—Jiuju Magnetizer

September 12, 2026

Irregularly shaped samarium-cobalt magnets have complex magnetic pole configurations. Combined with the high-temperature resistance and high coercive force of samarium-cobalt materials, this makes them highly prone to issues such as magnetic field non-uniformity and uneven magnetization during magnetization, placing high demands on tooling and process parameters.

Magnetization itself is a physical process that takes place in milliseconds; what truly slows down the overall production cycle are the manual loading, unloading, and alignment and calibration steps. In manual magnetization mode, workers must pick up and place each part individually and verify the polarity direction, which takes several seconds per part. Production capacity fluctuates significantly depending on the workers’ skill level and fatigue, and the strong magnetic field environment also poses safety hazards.
