Neodymium flat magnets min. MPL 200x30x30 / N38 are magnets made from neodymium in a flat form. They are known for their very strong magnetic properties, which are much stronger than standard ferrite magnets.
Thanks to their mighty power, flat magnets are regularly used in structures that need strong holding power.
The standard temperature resistance of flat magnets is 80°C, but depending on the dimensions, this value grows.
In addition, flat magnets commonly have different coatings applied to their surfaces, e.g. nickel, gold, or chrome, for enhancing their strength.
The magnet with the designation MPL 200x30x30 / N38 and a magnetic strength 183.51 kg which weighs a mere 1350 grams, making it the excellent choice for projects needing a flat magnet.

Neodymium flat magnets offer a range of advantages compared to other magnet shapes, which cause them being the best choice for a multitude of projects:
Contact surface: Thanks to their flat shape, flat magnets ensure a greater contact surface with adjacent parts, which can be 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 necessary for their operation.
Mounting: The flat form's flat shape makes mounting, particularly when it is required to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets allows creators greater flexibility in arranging them in structures, which is more difficult with magnets of more complex shapes.
Stability: In some applications, the flat base of the flat magnet can provide better stability, minimizing the risk of shifting or rotating. However, one should remember that the optimal shape of the magnet depends on the specific project and requirements. In some cases, other shapes, such as cylindrical or spherical, are more appropriate.

Attracted by magnets are ferromagnetic materials, such as iron, nickel, materials with cobalt and alloys of metals with magnetic properties. Moreover, magnets may weaker affect some other metals, such as steel. It’s worth noting that magnets are utilized in various devices and technologies.

The operation of magnets is based on the properties of their magnetic field, which arises from the ordered movement of electrons in their structure. The magnetic field of these objects creates attractive forces, which affect materials containing iron or other ferromagnetic substances.

Magnets have two main poles: north (N) and south (S), which interact with each other when they are oppositely oriented. Poles of the same kind, such as two north poles, repel each other.
Due to these properties, magnets are regularly used in magnetic technologies, such as motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the highest power of attraction, making them perfect for applications requiring strong magnetic fields. Moreover, the strength of a magnet depends on its dimensions and the materials used.

Not all materials react to magnets, and examples of such substances are plastics, glass, wooden materials or most gemstones. Moreover, magnets do not affect certain metals, such as copper, aluminum, copper, aluminum, and gold. Although these metals conduct electricity, do not exhibit ferromagnetic properties, meaning that they do not respond to a standard magnetic field, unless they are subjected to an extremely strong magnetic field.
It should be noted that high temperatures can weaken the magnet's effect. Every magnetic material has its Curie point, meaning that under such conditions, the magnet stops being magnetic. Interestingly, strong magnets can interfere with the operation of devices, such as navigational instruments, credit cards or electronic devices sensitive to magnetic fields. Therefore, it is important to exercise caution when using magnets.

A neodymium magnet N52 and N50 is a strong and powerful magnetic product designed as a plate, that provides strong holding power and versatile application. Good price, availability, durability and universal usability.

Advantages and disadvantages of neodymium magnets NdFeB.

Besides their magnetic performance, neodymium magnets are valued for these benefits:

They retain their attractive force for around 10 years – the loss is just ~1% (in theory),
They protect against demagnetization induced by surrounding magnetic influence very well,
By applying a shiny layer of gold, the element gains a clean look,
They have very high magnetic induction on the surface of the magnet,
Neodymium magnets are known for very high magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the magnetic form),
The ability for accurate shaping and customization to individual needs – neodymium magnets can be manufactured in multiple variants of geometries, which amplifies their functionality across industries,
Significant impact in advanced technical fields – they find application in data storage devices, rotating machines, clinical machines and technologically developed systems,
Relatively small size with high magnetic force – neodymium magnets offer strong power in compact dimensions, which allows for use in compact constructions

Disadvantages of NdFeB magnets:

They are fragile when subjected to a sudden impact. If the magnets are exposed to shocks, we recommend in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from cracks while also increases its overall resistance,
They lose field intensity at increased temperatures. Most neodymium magnets experience permanent reduction in strength when heated above 80°C (depending on the dimensions and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
Magnets exposed to moisture can corrode. Therefore, for outdoor applications, we advise waterproof types made of non-metallic composites,
Using a cover – such as a magnetic holder – is advised due to the challenges in manufacturing fine shapes directly in the magnet,
Potential hazard due to small fragments may arise, in case of ingestion, which is notable in the context of child safety. Moreover, tiny components from these assemblies can hinder health screening after being swallowed,
Higher purchase price is one of the drawbacks compared to ceramic magnets, especially in budget-sensitive applications

Caution with Neodymium Magnets

Do not place neodymium magnets near a computer HDD, TV, and wallet.

Neodymium magnets generate strong magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.

Under no circumstances should neodymium magnets be brought close to GPS and smartphones.

Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.

If you have a nickel allergy, avoid contact with neodymium magnets.

Studies show a small percentage of people have allergies to certain metals, including nickel. An allergic reaction often manifests as skin redness and rash. If you have a nickel allergy, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

Magnets made of neodymium are especially fragile, resulting in their breakage.

Magnets made of neodymium are fragile as well as will break if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal and coated with a shiny nickel plating, they are not as hard as steel. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.

Neodymium magnets can become demagnetized at high temperatures.

Despite the general resilience of magnets, their ability to maintain their magnetic potency can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.

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.

Magnets will jump and also touch together within a distance of several to around 10 cm from each other.

Neodymium magnets are the strongest magnets ever invented. Their strength can surprise 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.

Keep neodymium magnets away from people with pacemakers.

In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes with the operation of a heart pacemaker. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.

Magnets should not be treated as toys. Therefore, it is not recommended for children to have access to them.

Neodymium magnets are not toys. Do not allow children to play with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.

Warning!
