Neodymium Disc Magnet

This Neodymium Disc shaped magnet contains N50 Grade magnetic material which is one of the strongest grades available. Stronger than average grade magnets are suited to applications where space constraints create problems and make the use of a larger more powerful magnet impractical. Several disc magnets arranged with alternating poles within an assembly can make a powerful magnetic tool for holding or suspending heavy items from steel surfaces. Small disc magnets are often used inside plastic whiteboard markers and other low-tech applications where their high strength and light weight is an advantage. Since the 1980’s Neodymium discs have been instrumental in the development of sophisticated, high-tech Audio and Telephony equipment where their space-saving proportions, strength, sensitivity and accuracy enables them to convert sound vibrations into amplified electrical signals that can be transmitted or recorded for playback. Microphones and Loudspeakers use Neodymium magnet technology to produce high-fidelity, electrically amplified sound in a similar but converse operation to each other.

Disc shaped magnets attached to a surface with glue can also be very practical and versatile inclusions in handicraft projects, modelling, art and commercial advertising displays, exhibitions, outdoor markets and anywhere traditional fastening methods are inconvenient or unsuitable.

Frenergy has a comprehensive range of powerful Neodymium disc magnets in various diameters, pole orientations and grades that are able to suit nearly every application.

Production Flow Diagram
Demagnetization Curves
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. 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.

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.

FAQ

What Are Neodymium Disc Magnets?
Neodymium disc magnets are extremely strong and durable permanent magnets. Neodymium Rare Earth material possesses a powerfully strong magnetic force.
What Makes Neodymium Magnets So Strong?
Neodymium magnets are often referred to as super magnets because of their immense strength. Neodymium magnets are the strongest permanent magnets on the market. Neodymium is magnetic because it’s a ferromagnetic material. Neodymium is a rare-earth material, and when it is made to an alloy with iron and boron, it becomes the most powerful magnet on the market. The pull strength a Neodymium magnet can achieve is the strongest of the permanent magnets you can buy. It is so strong because it has a very high state of saturation, magnetization. So, the magnetic energy of the combination of Neodymium, iron, and boron can store, makes the alloy very magnetic.
How Powerful Are Neodymium Disc Magnets?
This tiny disc shaped N50 Grade magnet is deceptively strong for its size and can hold many times its own weight. Our Neodymium disc magnet measuring just 10mm x 3mm, is graded N50, has a pull force of 2.32kg and weighs just 3 grams. Many Neodymium magnets are more than 10 times stronger than the strongest ceramic magnets.
What Are the Uses for Neodymium Disc Magnets?
Because of their power to weight ratio, these small, powerful disc magnets are important components for manufacturers of hi-tech electronic devices and sound and telecommunications equipment. Delicate holding requirements in jewellery design or model-making applications are also where these small discs are ideal, because they can discreetly attract and bond two surfaces together. Small, strong disc magnets can be used for many applications where a simple pull-to-release type of attachment is required. These tiny Neodymium disc magnets are very inexpensive and can provide a unique and repeatable fastening solution for many bespoke designs and for a multitude of purposes.
Where Can Neodymium Disc Magnets Be Used?
Tradespeople use strong, Rare Earth disc magnets in work vehicles or toolboxes to support tools, nails, screws and other metallic items used while performing their daily duties. A magnet attached to a toolbelt makes the metal components they need easy to reach, especially in enclosed or difficult to access work areas. Plastic screens or sheets can be held in place temporarily on steel surfaces with small and powerful magnets, so other surfaces are covered and not damaged while the repairs or maintenance takes place. N50 Grade Neodymium is found inside the nickel coating of this disc and is one of the strongest grades. High-grade Neodymium material means extremely strong magnetic hold can be extracted from magnets that are relatively small which makes this type of magnet ideal for crafts, model making and arts.
How Do I Care for Neodymium Magnets?
The magnet material itself is brittle and prone to fracturing easily. Please avoid strong collisions between the magnet and any solid objects, as the magnet can be easily damaged. After use, please store the magnet in a dry and sealed environment to significantly increase its lifespan. Our strong magnets are protected with a corrosion-resistant Ni-Cu-Ni (Nickel-Copper-Nickel) coating plated on our magnet providing a shiny, rust-free and mirror-like finish. The nickel coating makes the magnet more resistant to corrosion.
Why Are Neodymium Magnets So Popular?
Neodymium magnets, such as disc magnets, are a vital component in many industries, including aviation, automotive, electronics and communications industries. Strong Neodymium magnets are an important component to generate movement or to produce renewable energy, a rapidly developing field of expertise which relies heavily on quality products that deliver what they promise. Super strong Neodymium magnets have enormous value in developing industries which rely on permanent and reliable magnetic hold.
Do Neodymium Magnets Have A Role In Renewable Energy?
Some forms of electric motors and generators, including cordless electric power tools and wind powered generators, use Rare Earth Neodymium magnets. Electric and hybrid vehicles rely heavily on round, Rare Earth disc magnets that allow them to operate independently or with far less reliance on fossil fuels.
What Are Other Uses for Neodymium Magnets?
Many types of electrical equipment use electromagnetic fields and often require a strong Neodymium permanent magnet to interact with the field and convert it into electric signals, data, audible sound, or in some cases, to activate certain procedures. These types of devices can include microphones, micro speakers, alarms and the actuators of equipment, including vital medical ventilators and respirators. The super strong Neodymium magnetic bond delivers countless solutions to homeowners, tradespeople and creative teams involved in theatre and television set design and construction, or who work in the performing and visual arts sector. Whether your business involves heavy duty lifting and bonding or displaying fine artwork or commercial signage, there is an extremely strong Neodymium disc to suit your holding requirements. Powerful, small disc magnets are often glued into position on hard surfaces or are sometimes sewn into soft materials so the garment or covering can attach to steel. These tiny magnets provide an ideal way of attaching and removing protective covers, privacy screens or shade cloth to a metal fixing point, which can include a metal washer or another disc magnet with the opposite pole.
