Magnetic properties of material N38
Physical properties of NdFeB
Shopping tips
Due to their strength, flat magnets are frequently applied in devices that require very strong attraction.
The standard temperature resistance of these magnets is 80°C, but with larger dimensions, this value can increase.
In addition, flat magnets often have different coatings applied to their surfaces, such as nickel, gold, or chrome, for enhancing their corrosion resistance.
The magnet named MPL 15x10x2 / N38 and a magnetic strength 1.93 kg with a weight of only 2.25 grams, making it the excellent choice for applications requiring a flat shape.
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: They are often used in various devices, such as sensors, stepper motors, or speakers, where the thin and wide shape is crucial for their operation.
Mounting: Their flat shape makes mounting, especially when there's a need to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets gives the possibility creators greater flexibility in arranging them in devices, 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, it's important to note that the optimal shape of the magnet depends on the specific application and requirements. In certain cases, other shapes, such as cylindrical or spherical, may be more appropriate.
Magnets have two poles: north (N) and south (S), which interact with each other when they are different. Similar poles, e.g. two north poles, act repelling on 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 indispensable for applications requiring strong magnetic fields. Additionally, the strength of a magnet depends on its size and the material it is made of.
It’s worth noting that high temperatures can weaken the magnet's effect. The Curie temperature is specific to each type of magnet, meaning that once this temperature is exceeded, the magnet stops being magnetic. Interestingly, strong magnets can interfere with the operation of devices, such as compasses, magnetic stripe cards and even medical equipment, like pacemakers. For this reason, it is important to exercise caution when using magnets.
Advantages and disadvantages of neodymium magnets NdFeB.
Apart from immense power, neodymium magnets have the following advantages:
- They do not lose their power (of the magnet). After about 10 years, their power decreases by only ~1% (theoretically),
- They are extremely resistant to demagnetization by external magnetic field,
- In other words, thanks to the glossy nickel, gold, or silver finish, the element gains an visually attractive appearance,
- They have exceptionally high magnetic induction on the surface of the magnet,
- Thanks to their high temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C and above...
- Thanks to the flexibility in shaping and the ability to adapt to specific requirements – neodymium magnets can be produced in various forms and dimensions, which amplifies their universality in usage.
- Key role in advanced technologically fields – are utilized in hard drives, electric drive mechanisms, medical equipment or other highly developed apparatuses.
Disadvantages of neodymium magnets:
- They are prone to breaking as they are fragile when subjected to a powerful impact. If the magnets are exposed to impacts, it is suggested using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
- They lose strength at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the form and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
- They rust in a humid environment - during outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
- The use of a cover or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
- Health risk arising from small pieces of magnets pose a threat, if swallowed, which is crucial in the context of children's health. Additionally, miniscule components of these products are able to complicate diagnosis when they are in the body.
Exercise Caution with Neodymium Magnets
You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.
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 away from these electronic devices.
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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.
Magnets attract each other within a distance of several to about 10 cm from each other. Remember not to put fingers between magnets or alternatively in their path when attract. Magnets, depending on their size, are able even cut off a finger or alternatively there can be a severe pressure or even a fracture.
Neodymium magnets are extremely fragile, they easily fall apart as well as can become damaged.
Neodymium magnets are extremely delicate, and by joining them in an uncontrolled manner, they will break. Neodymium magnets are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of collision between the magnets, small metal fragments can be dispersed in different directions.
Neodymium magnets are over 10 times stronger than ferrite magnets (the ones in speakers), and their power 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.
Neodymium magnets can become demagnetized at high temperatures.
Although magnets have demonstrated their effectiveness up to 80°C or 175°F, the temperature can vary depending on the type, shape, and intended use of the specific magnet.
Dust and powder from neodymium magnets are flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Neodymium magnets are not recommended for people with pacemakers.
Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.
Do not bring neodymium magnets close to GPS and smartphones.
Magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, 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. 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.
