The Neodymium Circular Piece Magnet for Intense Magnetic Fields is a premium, high-performance component engineered to generate some of the strongest magnetic fields available in permanent magnets—making it the top choice for applications where extreme magnetic force, compact size, and reliability are essential. Crafted from neodymium-iron-boron (NdFeB)—the strongest permanent magnet material on the market—this circular magnet delivers exceptional magnetic flux density, far exceeding that of ceramic, alnico, or samarium cobalt alternatives. Available in diameters from 10mm to 150mm and thicknesses from 2mm to 25mm, it produces intense magnetic fields that can reach up to 1.4 tesla (depending on size and grade), with holding forces ranging from 10kg to 400kg for standard sizes (and even higher for custom designs).

A key advantage of this neodymium circular magnet is its unparalleled strength-to-weight ratio. Compared to other magnet types that generate similar magnetic fields, neodymium magnets are significantly smaller and lighter—critical for applications where space and weight are at a premium. For example, in magnetic resonance imaging (MRI) machines used in medical diagnostics, small neodymium circular piece magnets (20mm to 30mm in diameter) are integrated into the machine’s gradient coils. These magnets help generate the intense, localized magnetic fields needed to produce detailed images of the human body. The compact size of the neodymium magnets allows the MRI machine to be more portable (compared to older models using superconducting magnets), making advanced medical imaging accessible in smaller clinics or remote areas.

In industrial magnetic separation systems—used to extract ferrous contaminants from raw materials like coal, ore, or plastic—the Neodymium Circular Piece Magnet’s intense magnetic field is a game-changer. A 100mm diameter neodymium circular magnet can be installed in a separator drum, where its strong field attracts even tiny iron particles (as small as 0.1mm) that would pass through weaker magnets. This level of separation is critical for protecting expensive downstream equipment (like crushers or extruders) from damage and ensuring the final product meets strict quality standards. The circular shape of the magnet ensures the magnetic field is evenly distributed around the drum, maximizing the separation efficiency.

High-performance motors and generators also rely on this neodymium circular magnet to deliver exceptional power. In electric vehicles (EVs), for instance, 80mm diameter neodymium circular piece magnets are used in the traction motor’s rotor. The intense magnetic field generated by these magnets interacts with the stator’s electrical current to produce high torque, enabling the EV to accelerate quickly and operate efficiently. The small size of the neodymium magnets allows the motor to be more compact and lightweight, improving the EV’s battery range and overall performance. Similarly, in wind turbines, large neodymium circular magnets (120mm to 150mm in diameter) are used in the generator to convert wind energy into electricity. The intense magnetic field ensures efficient energy conversion, even in low-wind conditions, making wind power more viable as a renewable energy source.

To protect the neodymium magnet from corrosion and damage, it is coated with a durable layer of nickel-copper-nickel plating, epoxy, or gold. This coating not only extends the magnet’s lifespan but also makes it suitable for use in harsh environments—like marine applications (where saltwater corrosion is a risk) or industrial settings with high humidity. For high-temperature applications (like in aircraft engines), neodymium magnets with a samarium cobalt blend are available, which can withstand temperatures up to 200°C without losing their intense magnetic fields.

Whether used in medical imaging, industrial separation, EV motors, or wind turbines, the Neodymium Circular Piece Magnet for Intense Magnetic Fields delivers the extreme magnetic force needed for the most demanding applications. Its combination of high strength, compact size, and durability makes it a versatile and reliable solution for industries pushing the boundaries of performance.
