Neodymium flat magnets i.e. MPL 50x50x10 / N38 are magnets created from neodymium in a flat form. They are appreciated for their very strong magnetic properties, which are much stronger than standard ferrite magnets.
Due to their power, flat magnets are regularly applied in devices that require strong holding power.
Most common temperature resistance of flat magnets is 80°C, but with larger dimensions, this value rises.
Additionally, flat magnets commonly have special coatings applied to their surfaces, such as nickel, gold, or chrome, for enhancing their durability.
The magnet with the designation MPL 50x50x10 / N38 and a magnetic force ${capacity} kg which weighs only ${weight} grams, making it the excellent choice for projects needing a flat magnet.

Neodymium flat magnets present a range of advantages versus other magnet shapes, which lead to 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 other components, which is beneficial in applications needing a stronger magnetic connection.
Technology applications: These magnets are often used in different devices, such as sensors, stepper motors, or speakers, where the thin and wide shape is important for their operation.
Mounting: The flat form's flat shape makes it easier mounting, particularly when it is necessary to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets gives the possibility designers a lot of flexibility in arranging them in structures, which is more difficult with magnets of other shapes.
Stability: In some applications, the flat base of the flat magnet can provide better stability, reducing the risk of sliding or rotating. However, it's important to note that the optimal shape of the magnet is dependent on the specific application and requirements. In certain cases, other shapes, such as cylindrical or spherical, are a better choice.

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

Magnets work thanks to the properties of the magnetic field, which arises from the ordered movement of electrons in their structure. Magnetic fields of magnets creates attractive interactions, which attract objects made of iron or other ferromagnetic substances.

Magnets have two poles: north (N) and south (S), which attract each other when they are oppositely oriented. Similar poles, such as two north poles, act repelling on each other.
Due to these properties, magnets are regularly used in magnetic technologies, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the highest power of attraction, making them perfect for applications requiring powerful magnetic fields. Moreover, 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 items, wooden materials and most gemstones. Furthermore, 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. 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 compasses, credit cards or electronic devices sensitive to magnetic fields. For this reason, it is important to exercise caution when using magnets.

Advantages and disadvantages of neodymium magnets

Neodymium magnets, also known as NdFeB magnets, are currently the strongest permanent magnets available on the market. Their exceptional magnetic properties make them suitable for various industries, technologies, and everyday life. Below are the key advantages:

Immense attractive force: Even small neodymium magnets generate a very strong magnetic field.
High coercivity: They are resistant to demagnetization by external magnetic fields.
Wide operating temperature range: Standard neodymium magnets operate up to 80°C, with special versions up to 230°C.
Variety of shapes and sizes: Available in many forms, making them easy to adapt to specific applications.
Relatively low price compared to strength: They offer the best strength-to-price ratio among all magnets.
Longevity: With proper use, they retain their magnetic properties for many years.
Versatility of applications: From electric motors to speakers, separators, toys, and jewelry.

Despite numerous advantages, neodymium magnets also have certain disadvantages to consider:

Brittleness: They are hard but brittle and prone to cracking or chipping upon impact.
Limited operating temperature for standard versions: Above the Curie temperature, they lose their magnetic properties.
Strong magnetic field can be dangerous: They can damage electronics, magnetic cards, and pose a risk of attracting metal objects with great force.
Difficulties in mechanical processing: Due to their hardness and brittleness, processing them is complex.

Be Cautious with Neodymium Magnets

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.

Do not give neodymium magnets to youngest children.

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 severe injuries, and even death.

Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.

If the joining of neodymium magnets is not under control, then they may crumble and also crack. You can't move them to each other. At a distance less than 10 cm you should hold them extremely strongly.

Keep neodymium magnets away from GPS and smartphones.

Neodymium magnets produce intense magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

You should keep neodymium magnets at a safe distance from the wallet, computer, and TV.

Neodymium magnets produce strong magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also destroy devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

Neodymium magnets are the strongest magnets ever created, and their power can shock you.

Familiarize yourself with our information to properly handle these magnets and avoid significant swellings to your body and prevent disruption to the magnets.

Magnets made of neodymium are known for being fragile, which can cause them to shatter.

Neodymium magnetic are highly fragile, and by joining them in an uncontrolled manner, they will crack. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. At the moment of collision between the magnets, sharp metal fragments can be dispersed in different directions.

Neodymium magnets can demagnetize at high temperatures.

Although magnets are generally resilient, 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.

Keep neodymium magnets away from people with pacemakers.

Neodymium magnets produce strong magnetic fields that can interfere 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.

The magnet coating is made of nickel, so be cautious if you have an 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.
