Neodymium Block Magnet – 8mm x 3mm x 3.5mm | N50
This compact N50 neodymium block magnet measures 8mm long, 3mm wide and 3.5mm high. Despite its small size, it delivers a pull force of approximately 1.04kg and a surface magnetic flux reading of approximately 5,861 Gauss. Its rectangular shape provides broad, flat contact surfaces for secure holding in space-limited applications.
Product Specifications
- Material: Neodymium rare earth magnet (NdFeB)
- Grade: N50
- Dimensions: 8mm (L) x 3mm (W) x 3.5mm (H)
- Pull force: Approximately 1.04kg
- Surface magnetic flux: Approximately 5,861 Gauss
- Shape: Rectangular block
- Part number: B-W3H3.5L8-N50
Common Applications
The high strength-to-size ratio of this small rare earth block magnet makes it suitable for precision holding, sensing and assembly tasks where installation space is limited.
- Scale models, miniatures and craft projects
- Magnetic closures and concealed catches
- Electronic devices, sensors and warning systems
- Speakers, microphones and compact audio equipment
- Product prototypes and small engineering assemblies
- Displays, fixtures and lightweight holding systems
Why Choose an N50 Block Magnet?
N50 is a high neodymium grade that provides strong magnetic performance from a very compact magnet. The flat pole faces help create reliable contact with clean, flat ferrous surfaces, making this magnet useful in commercial, industrial, technical and hobby applications.
Important: Pull force is measured under ideal test conditions. Actual holding strength may be reduced by air gaps, paint, rust, uneven surfaces, thin steel or sideways loading.
No FAQ available
NB: Ranges are indicative for product category, please check individual products for specic values within that range.
The most common coating for Neodymium magnets is Nickel + Copper + Nickel (Ni + Cu + Ni). This coating offers the magnet relatively good protection from corrosion and passive applications. If the magnet will be exposed to moisture or liquid then consider the use of an organic coating such as Epoxy. A hard wearing coating, Epoxy is suited to applications where the magnet will come under some friction or knocking.
Magnets are readily available in Blocks, Discs, Cylinders & Rings. AMF Magnetics specializes in the supply of short-run prototype magnets including Arc Segments, various magnetic orientations etc. If you need a magnet size that we don't carry in stock, submit a Design-a-Magnet enquiry for a quote on your custom magnet design.
Neodymium magnets are offered in several different grades. The first section N30-54 has an operating temperature of up to 80 degrees. Most of our stock only goes up to N38. The second section, denoted with the "M" prefix after the grade has an operating temperature 100 degrees. After this the grades are "H", "SH", "UH" & "EH". In order for the magnet to withstand a higher operating temperature, during production more of the raw material PrNd is incorporated as these elements have a naturally occurring resistance to high temperatures.
