Neodymium flat magnets min. MPL 30x20x10 / N38 are magnets made from neodymium in a flat form. They are known for their extremely powerful magnetic properties, which are much stronger than standard iron magnets.
Due to their power, flat magnets are regularly used in structures that need exceptional adhesion.
The standard temperature resistance of these magnets is 80°C, but depending on the dimensions, this value grows.
Moreover, flat magnets often have special coatings applied to their surfaces, e.g. nickel, gold, or chrome, to improve their durability.
The magnet named MPL 30x20x10 / N38 i.e. a lifting capacity of 17.29 kg which weighs only 45 grams, making it the ideal choice for applications requiring a flat shape.

Neodymium flat magnets provide a range of advantages compared to other magnet shapes, which make 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 can be beneficial in applications requiring a stronger magnetic connection.
Technology applications: These are often used in different devices, such as sensors, stepper motors, or speakers, where the thin and wide shape is necessary for their operation.
Mounting: This form's flat shape makes mounting, especially when it is required to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets allows creators a lot of flexibility in placing 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, reducing 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 certain cases, other shapes, such as cylindrical or spherical, are more appropriate.

How do magnets work? Magnets attract ferromagnetic materials, such as iron elements, nickel, materials with cobalt or alloys of metals with magnetic properties. Moreover, magnets may lesser affect some other metals, such as steel. Magnets are used in many fields.

The operation of magnets is based on the properties of the magnetic field, which is generated by the movement of electric charges within their material. Magnetic fields of these objects creates attractive forces, which attract materials containing cobalt or other ferromagnetic substances.

Magnets have two main poles: north (N) and south (S), which interact with each other when they are different. Similar poles, e.g. two north poles, repel each other.
Due to these properties, 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 ideal for applications requiring powerful magnetic fields. Moreover, the strength of a magnet depends on its size and the materials used.

Magnets do not attract plastic, glass, wood or precious stones. Moreover, magnets do not affect certain metals, such as copper items, aluminum, gold. These metals, although they are conductors of electricity, do not exhibit ferromagnetic properties, meaning that they remain unaffected by a magnet, unless exposed to a very 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 once this temperature is exceeded, the magnet stops being magnetic. Additionally, strong magnets can interfere with the operation of devices, such as navigational instruments, magnetic stripe cards or medical equipment, like pacemakers. For this reason, it is important to avoid placing magnets near such devices.

A neodymium plate magnet of class N50 and N52 is a powerful and highly strong magnetic product shaped like a plate, that provides high force and universal application. Attractive price, fast shipping, durability and universal usability.

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to their long-term stability, neodymium magnets provide the following advantages:

They virtually do not lose strength, because even after 10 years, the performance loss is only ~1% (according to literature),
They remain magnetized despite exposure to strong external fields,
The use of a polished gold surface provides a refined finish,
The outer field strength of the magnet shows advanced magnetic properties,
Thanks to their exceptional temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C or more,
With the option for tailored forming and targeted design, these magnets can be produced in numerous shapes and sizes, greatly improving application potential,
Significant impact in advanced technical fields – they are utilized in data storage devices, rotating machines, healthcare devices or even technologically developed systems,
Relatively small size with high magnetic force – neodymium magnets offer intense magnetic field in tiny dimensions, which allows for use in miniature devices

Disadvantages of magnetic elements:

They are prone to breaking when subjected to a heavy impact. If the magnets are exposed to physical collisions, it is advisable to use in a protective case. The steel housing, in the form of a holder, protects the magnet from damage while also increases its overall resistance,
Magnets lose power when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible magnetic decay (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,
They rust in a moist environment, especially when used outside, we recommend using encapsulated magnets, such as those made of rubber,
The use of a protective casing or external holder is recommended, since machining fine details in neodymium magnets is difficult,
Health risk due to small fragments may arise, when consumed by mistake, which is important in the protection of children. Furthermore, tiny components from these magnets can disrupt scanning once in the system,
Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications

Exercise Caution with Neodymium Magnets

Neodymium magnets can become demagnetized at high temperatures.

Although magnets are generally resilient, their ability to retain their magnetic strength 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 are the strongest magnets ever created, and their power can shock you.

On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.

Neodymium magnets are known for being fragile, which can cause them to shatter.

Neodymium magnets are fragile and will crack if allowed to collide with each other, even from a distance of a few centimeters. They are coated with a shiny nickel plating similar to steel, but they are not as hard. 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 attract to each other, pinch the skin, and cause significant injuries.

Magnets attract each other within a distance of several to around 10 cm from each other. Don't put your fingers in the path of magnet attraction, because a major injury may occur. Depending on how massive the neodymium magnets are, they can lead to a cut or alternatively a fracture.

Keep neodymium magnets away from people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

The magnet coating contains nickel, so be cautious if you have a nickel allergy.

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.

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

Strong magnetic fields emitted by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.

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.

Magnets are not toys, children should not play with them.

Neodymium magnets are not toys. Be cautious and make sure no child plays with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.

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.
