Neodymium Disc Magnet - 3mm x 1.5mm

Magnetic Product Description:

Made from strong Rare Earth magnetic material, this permanent magnet is extremely strong for its size. It has a magnetic flux reading of 4455 Gauss and a strong magnetic pull force of 160 grams. This small-sized, circular disc-shaped Rare Earth Disc has a diameter of 3mm and a height of 1.5mm. The nickel coating provides for superior corrosion resistance, enabling long-term use with minimal wear.


Uses for our Rare Earth Disc Magnets:

This miniature Neodymium Disc is one of the smallest magnets in the AMF range and its tiny proportions make it incredibly versatile. This type of Neodymium magnet is ideal for applications where the magnet needs to be discreet yet effective. Small rare earth magnets can be used as a single magnet for lightweight projects or in a series for a stronger hold.
This small disc is popularly used in arts, crafts projects and hobby areas to hold decorations, artworks, models and to display retail items. Model and jewellery makers use these tiny but strong magnetic discs for closure or clamping mechanisms.

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.

Great price, excellent service.

I am using these to fix turrets on my 15mm Renegade Legion Grav Tanks, as well as fitting them to the clear acrylic rod that acts as a stand. This allows for the turrets to traverse and the stands to be removed for storage.

The quality I was looking for

I am working on a magnetic coupling system for model railways and the magnet part of the system needs to exhibit consistent quality based on it's specifications. Your product has done that for me and therefore it's one part of the system I no longer have to be concerned about.........thanks for a good product.

Magnetic wing mod

Needed some magnets for a job on an RC airplane. Works great, holds wing on during loops but allows wing to detach in crash, saving broken wing.
