Product Description
Products Description
Powerful N52 Magnets Customized Block 30x20x10mm Strong Neodymium Square Magnet
Powerful: Our product has a grade of N52, which is the highest grade of neodymium magnets available on the market. This means that our product has a very high magnetic flux density of up to 14,800 gauss, which is much higher than the average of 1000-2000 gauss for other neodymium magnets3. This means that our product can provide stronger magnetic force and longer magnetic range for your applications. Customized: Our product has a standard size of 30x20x10mm, which is a common size for block magnets. However, we can also customize the size according to your requirements, as long as it is within the range of 1-100 mm for length, width, and height. You can specify the size you want when you place your order, and we will make it for you as soon as possible. Square: Our product is a square magnet, which is a simple and versatile shape that can be used for many applications. You can use our product to make magnetic holders, clamps, mounts, hooks, etc. You can also use our product to create various patterns, designs, and artworks with other magnets. Our product can be easily cut, drilled, or glued to fit your needs. Durable and reliable: Our product is coated with nickel, which is a common and effective coating for neodymium magnets. Nickel coating can protect the magnet from corrosion, oxidation, and abrasion, and enhance its appearance and durability. Our product is also tested and certified by ISO 9001, CE, and RoHS, which means that it meets the international standards of quality, safety, and environmental protection.

Magnet Plating and Coating Options
The following is a list and description of common plating options for custom magnets.Why do magnets need to be plated?
★ Harsh Environments
Platings vary in their tolerance of different harsh chemicals and abrasion. Salt and humidity in regions near the ocean are
commonly overlooked when selecting a plating. Be sure to consider the magnets environment when selecting a plating.
★ Oxidization (Rust)
NdFeB magnets will oxidize(rust) if left exposed. When a plating wears down or cracks, the exposed area will oxidize. An oxidized area will not result in complete degradation of the magnet, only the oxidized area will lose its strength. However the magnet will lose some structural integrity and become more susceptible to breakage.

However the magnet will lose some structural integrity and become more susceptible to breakage.
★ Durability
Depending on shape, permanent magnet substrate is brittle. A multilayered metal plating like nickel or zinc improves the magnets resistance to chipping and wear, particularly around corners.

The most common type of plating for neodymium magnets Nickel (Ni-Cu-Ni) Intended for indoor use. It has proven to be very resilient when subjected to normal wear and tear. However it will corrode oudoors in prolonged exposure to salt water, salty air,or harsh chemicals.
Magnetization Direction
A Magnetic field is an invisible flux moving from one end of the magnet to the other. Shown in Figure1. The flux consists of
moving or spinning electrically charged particles invisible to the eye. If the max working temperature meet the requirement ,permanent magnets can retain the magnetic field for very long time even forever. Magnets have potential energy which means that they have the ability to conserve energy. The magnet will display or release some of its conserved energy when pulling towards or attaching to something then conserve or store the energy that the user exerts when pulling it off.

The magnet will display or release some of its conserved energy when pulling towards or attaching to something then conserve or store the energy that the user exerts when pulling it off.
Every magnet has a north seeking and a south seeking face on opposite ends. The north face of one magnet will always be attracted towards the south face of another magnet.
Application Fields
Neodymium magnets are strong magnets,frequently used for many types of sectors, commercial, industrial & technical applications where strong permanent magnets are required. Due to their high-magnetic strength, components that previously had to be large and heavy can now be miniaturized by using Neodymium magnet material.Common Applications: holding systems requiring very high holding forces, sensors, reed switches, hard disc drives, audio equipment, acoustic pick-ups, headphones & loudspeakers, MRI scanners, magnetically coupled pumps · motors & generators, magnetic tool holders, magnetic bearings, door catches, dental instruments, medical devices, magnetic separators, lifting machinery, crafts & model making, hanging artwork, levitation devices, POP displays, commercial signage, packaging closures, jewelry clasps & more.
