Neodymium Block Magnet – 7mm x 3mm x 7mm with 3.5mm Hole | N35 | Side Magnetised
The Neodymium Block Magnet – 7mm x 3mm x 7mm with 3.5mm Hole | N35 | Side Magnetised is a compact, high-strength rare earth mounting magnet designed for applications requiring secure mechanical fixing and a magnetic field that is directed through the sides of the magnet rather than its thickness. Manufactured from premium N35 grade neodymium (NdFeB), this permanent magnet combines excellent magnetic performance with a precision 3.5mm through-hole, allowing it to be securely mounted using screws, rivets, pins, or custom fasteners.
Measuring 7mm long x 3mm wide x 7mm high, this block magnet features a 3.5mm centre hole for quick and reliable installation. Unlike standard block magnets, this model is side magnetised, meaning the north and south poles are located on the 7mm x 3mm side faces rather than the larger top and bottom surfaces. This unique magnetisation direction makes it ideal for specialised engineering applications where the magnetic field needs to operate horizontally or interact with adjacent components in a specific orientation.
Its compact dimensions and strong magnetic field make this magnet suitable for industrial automation, magnetic latches, sensors, positioning systems, fixtures, electronic devices, product design, and custom manufacturing projects. The nickel-plated finish provides excellent resistance to corrosion while enhancing durability for long-term use in indoor environments.
Whether you're designing a precision assembly, developing a prototype, or creating a custom magnetic mechanism, the 7mm x 3mm x 7mm Side Magnetised Neodymium Block Magnet delivers reliable performance in a compact and versatile package.

Why Choose a Side Magnetised Block Magnet?
Unlike conventional block magnets that are magnetised through their thickness, this magnet is side magnetised, creating a magnetic field across the side faces. This unique orientation is particularly useful when magnetic attraction or sensing is required from the sides of the magnet rather than from the top and bottom surfaces.
The integrated 3.5mm mounting hole allows the magnet to be securely fastened into equipment, machinery, fixtures, or custom assemblies without relying on adhesives. This provides a stronger, more reliable installation in applications exposed to vibration, repeated movement, or regular servicing.
Manufactured from N35 grade neodymium, this compact magnet delivers significantly greater holding power than ferrite magnets of similar dimensions, making it an excellent choice where installation space is limited but strong magnetic performance is required.

Please Note
This magnet is side magnetised, meaning the north and south poles are located on the side faces rather than the top and bottom surfaces. Please ensure this magnetisation direction is suitable for your intended application before purchasing.
Neodymium magnets are extremely powerful for their size and should be handled carefully to prevent pinch injuries or damage caused by sudden attraction to steel objects or other magnets.
Do not overtighten mounting screws or fasteners, as excessive force may crack the magnet. Neodymium magnets are brittle and should not be drilled, machined, or cut after manufacture.
Keep this product away from pacemakers, medical implants, magnetic storage devices, and sensitive electronic equipment. Actual magnetic performance will vary depending on the mating material, air gap, alignment, and operating conditions.

Surface Treatment
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.
Range and Tolerance
Magnets are readily available in Blocks, Discs, Cylinders & Rings. We 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.
Magnetic Properties
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.
