China Neodymium And Ferrite Magnets Manufacturer & Supplier 
If you need to purchase very small magnets, neodymium material is generally preferred due to its strong magnetism, which is important for most applications. Our website also provides many samples of tiny neodymium magnets. For square-shaped neodymium magnets, what is the smallest size that can be processed?
Generally speaking, the minimum processable size for conventional sintered neodymium square magnets is around 1x1x0.5mm, which is the specification that most magnet manufacturers can stably produce in bulk at present. If the size continues to decrease, the processing difficulty will increase significantly, and the product yield will also be very low.
Can it be processed even smaller?
It's possible that some leading magnet manufacturers can help, but if your order quantity is too small, they generally won't cooperate. You can keep looking.

In terms of applications, these miniature square magnets are primarily used in consumer electronics, such as TWS Bluetooth earphones, smartwatches, mobile phone camera modules, digital pens and smart glasses, where they can be utilised for magnetic positioning, Hall effect switch activation, flip-cover detection and miniature loudspeakers.
They can also be used in medical devices and precision instruments, such as miniature sensors, detection devices, precision positioning mechanisms and single-use medical devices.
The above is an introduction to the minimum size that can be processed for neodymium square magnets. Currently, there is an increasing number of customers who require these tiny square magnets and ultra-thin round magnets. If your company's products require these small magnets, please contact our company for a quotation.
