Neodymium flat magnets i.e. MPL 10x5x1.5 / N38 are magnets created from neodymium in a rectangular form. They are appreciated for their exceptionally potent magnetic properties, which surpass ordinary ferrite magnets.
Thanks to their high strength, flat magnets are commonly used in structures that need very strong attraction.
Most common temperature resistance of these magnets is 80 °C, but depending on the dimensions, this value rises.
In addition, flat magnets commonly have different coatings applied to their surfaces, such as nickel, gold, or chrome, for enhancing their corrosion resistance.
The magnet with the designation MPL 10x5x1.5 / N38 i.e. a magnetic force 0.84 kg with a weight of only 0.56 grams, making it the excellent choice for applications requiring a flat shape.

Neodymium flat magnets present a range of advantages compared to other magnet shapes, which cause them being an ideal choice for a multitude of projects:
Contact surface: Due to their flat shape, flat magnets ensure a larger contact surface with adjacent parts, which is beneficial in applications requiring a stronger magnetic connection.
Technology applications: These magnets are often used in various devices, e.g. sensors, stepper motors, or speakers, where the flat shape is important for their operation.
Mounting: This form's flat shape makes mounting, particularly when it is required to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets permits creators greater flexibility in placing them in devices, which is more difficult with magnets of more complex shapes.
Stability: In certain applications, the flat base of the flat magnet may offer better stability, minimizing the risk of shifting or rotating. However, it's important to note that the optimal shape of the magnet depends on the specific application and requirements. In some cases, other shapes, like cylindrical or spherical, are a better choice.

Magnets attract ferromagnetic materials, such as iron, nickel, materials with cobalt and special alloys of ferromagnetic metals. Additionally, magnets may weaker affect some other metals, such as steel. Magnets are used in many fields.

The operation of magnets is based on the properties of their magnetic field, which is generated by the movement of electric charges within their material. Magnetic fields of magnets creates attractive forces, which affect materials containing nickel or other magnetic materials.

Magnets have two main poles: north (N) and south (S), which attract each other when they are different. Poles of the same kind, e.g. two north poles, act repelling on each other.
Thanks to this principle of operation, magnets are often used in electrical devices, such as motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the greatest strength of attraction, making them perfect for applications requiring powerful magnetic fields. Additionally, the strength of a magnet depends on its size and the materials used.

Not all materials react to magnets, and examples of such substances are plastics, glass, wooden materials and precious stones. Furthermore, magnets do not affect most metals, such as copper, aluminum, items made of gold. These metals, although they are conductors of electricity, do not exhibit ferromagnetic properties, meaning that they do not respond to a standard magnetic field, unless exposed to a very strong magnetic field.
It should be noted that extremely high temperatures, above the Curie point, cause a loss of magnetic properties in the magnet. The Curie temperature is specific to each type of magnet, meaning that under such conditions, the magnet stops being magnetic. Additionally, strong magnets can interfere with the operation of devices, such as navigational instruments, credit cards and even electronic devices sensitive to magnetic fields. For this reason, it is important to avoid placing magnets near such devices.

A neodymium magnet in classes N52 and N50 is a strong and powerful magnetic piece designed as a plate, that provides strong holding power and universal application. Good price, 24h delivery, stability and universal usability.

Advantages and disadvantages of neodymium magnets NdFeB.

Apart from their consistent power, neodymium magnets have these key benefits:

They retain their attractive force for almost ten years – the loss is just ~1% (based on simulations),
They remain magnetized despite exposure to magnetic surroundings,
The use of a decorative gold surface provides a refined finish,
They possess significant magnetic force measurable at the magnet’s surface,
Thanks to their high temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C or more,
Thanks to the freedom in shaping and the capability to adapt to unique requirements, neodymium magnets can be created in various configurations, which expands their usage potential,
Wide application in new technology industries – they serve a purpose in data storage devices, electromechanical systems, medical equipment as well as high-tech tools,
Compactness – despite their small size, they deliver powerful magnetism, making them ideal for precision applications

Disadvantages of neodymium magnets:

They are fragile when subjected to a heavy impact. If the magnets are exposed to mechanical hits, it is advisable to use in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from damage while also enhances its overall resistance,
Magnets lose pulling force when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible performance loss (influenced by the magnet’s profile). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
Due to corrosion risk in humid conditions, it is recommended to use sealed magnets made of rubber for outdoor use,
The use of a protective casing or external holder is recommended, since machining threads in neodymium magnets is restricted,
Safety concern linked to microscopic shards may arise, when consumed by mistake, which is significant in the family environments. It should also be noted that minuscule fragments from these products may disrupt scanning if inside the body,
In cases of large-volume purchasing, neodymium magnet cost is a challenge,

Exercise Caution with Neodymium Magnets

Keep neodymium magnets far from children.

Remember that neodymium magnets are not toys. Be cautious and make sure no child plays with them. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even death.

Neodymium magnets are the most powerful magnets ever invented. Their power can shock you.

Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional damage to the magnets.

The magnet is coated with nickel - be careful if you have an allergy.

Studies clearly indicate a small percentage of people who suffer from metal allergies such as nickel. An allergic reaction often manifests as skin redness and rash. If you have a nickel allergy, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Neodymium magnets can become demagnetized at high temperatures.

In certain circumstances, Neodymium magnets may experience demagnetization when subjected to high temperatures.

Keep neodymium magnets away from TV, wallet, and computer HDD.

Strong fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

Dust and powder from neodymium magnets are highly flammable.

Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Keep neodymium magnets as far away as possible from GPS and smartphones.

Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.

Neodymium magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant injuries.

Neodymium magnets jump and also touch each other mutually within a distance of several to around 10 cm from each other.

People with pacemakers are advised to avoid neodymium magnets.

Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

Magnets made of neodymium are highly fragile, they easily fall apart as well as can crumble.

Magnets made of neodymium are extremely fragile, and by joining them in an uncontrolled manner, they will crumble. Neodymium magnetic are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of connection between the magnets, sharp metal fragments can be dispersed in different directions.

Caution!
