N42 Neodymium Magnet Product Overview

Get into our N42 Neodymium Magnet! It’s a high-strength magnet that brings you great magnetic power and reliability. First, we make it from premium NdFeB material. Then we coat it with nickel. This magnet stands out in many applications where a strong magnetic force and long-lasting durability are required. Whether you’re using it in electronic products, speakers, or industrial applications, it always delivers top performance.

N42 Neodymium Magnet Core Specifications

Grade: N42. This grade means the magnet has strong magnetic properties and can handle tasks that require a high level of magnetic attraction.
Shape: Round. The round shape offers great symmetry and is easy to integrate into various setups, from small electronic devices to large industrial machinery.
Material: NdFeB Magnet. As a powerful magnetic material, NdFeB (neodymium-iron-boron) is well known for its high magnetic energy product, meaning it can generate a strong magnetic field in a compact form.
Coating: Nickel. The nickel coating serves multiple purposes. First, it provides excellent corrosion resistance, protecting the magnet from environmental factors like moisture and chemicals. Second, it gives the magnet a smooth and professional look.
Size: Customized. Whether you need a small round magnet for a small electronic device or a larger one for an industrial application, we can adjust the size to fit your specific requirements.
Magnetic Direction: Axially magnetized, diametrally magnetized, or magnetized in another way, depending on thickness. This flexibility allows the magnet to be optimized for your specific magnetic circuit design.
Tolerance: ±05%. This high precision ensures the magnet will fit and function as expected in your application, whether it’s for a precise electronic component or a large-scale industrial project.

N42 Neodymium Magnet Product Advantages

Strong Magnetism: N42 grade provides a strong magnetic pull. Perfect for tasks such as lifting metal objects in industrial applications or providing a magnetic field in a speaker.
Durable Coating: The nickel coating is not just for looks. It forms a protective barrier against corrosion, extending the magnet’s life. Suitable for use in harsh environments, outdoor industrial applications, or high-humidity areas.
Multi-Application: This magnet is multi-purpose. It’s used in electronic products as sensors or actuators. In speaker magnets, it improves sound quality by providing a stable and strong magnetic field. In industrial magnets, it’s used in lifting equipment, magnetic separators, etc. Even in jewelry, magnets are used for secure clasps and solenoids, and motor magnets for efficient operation.
Precise Tolerance: ±05,% so you can trust our magnets will fit in your application perfectly.

N42 Neodymium Magnet Application Scenarios

Electronic Products: In small electronic devices like smartphones, tablets, and laptops, these round N42 magnets can be used in components such as sensors (e.g., magnetic field sensors for navigation) or actuators (e.g., in small motors for camera autofocus). They are small and strong, perfect for these precise applications.
Speaker Magnet: In speakers, the N42 Neodymium Magnet is crucial. It provides a stable magnetic field that interacts with the speaker’s voice coil, converting electrical signals into sound waves. Strong magnetism means clear, powerful, and high-quality sound, whether it’s in a home audio system or a professional studio monitor.
Industrial Magnet: In industrial applications, these magnets are used in many ways. For example, in magnetic lifting equipment, they can lift metal objects with ease, improving material handling efficiency. In magnetic separators, they separate ferromagnetic impurities from other materials, ensuring end product purity in processes like mining or food production.
Jewelry Magnet: In the jewelry industry, these magnets are used for secure and easy-to-use clasps. They allow for quick and hassle-free opening and closing of jewelry pieces like necklaces and bracelets, while still keeping the jewelry securely fastened.
Solenoid: In solenoid-based systems, such as in automotive fuel injectors or industrial valves, the magnet creates the magnetic field to actuate the solenoid. The strong magnetic force of N42 grade means the solenoid operates fast and efficiently.
Motor Magnet: In motors, whether it’s a small electric motor in a toy or a large industrial motor, these magnets provide the magnetic force for rotation. High magnetic strength of N42 grade means more efficient energy conversion, resulting in more powerful and energy-efficient motors.
