Advantages as well as disadvantages of Nd2Fe14B magnets.
Strengths
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (according to literature),
- Magnets very well defend themselves against demagnetization caused by external fields,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to look better,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of exact machining and optimizing to specific requirements,
- Universal use in modern technologies – they find application in hard drives, drive modules, medical devices, and industrial machines.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Limitations
- Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- Due to limitations in realizing nuts and complicated shapes in magnets, we recommend using casing - magnetic mount.
- Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small components of these products can be problematic in diagnostics medical after entering the body.
- With large orders the cost of neodymium magnets can be a barrier,
Lifting parameters
Maximum magnetic pulling force – what contributes to it?
- using a base made of high-permeability steel, functioning as a ideal flux conductor
- whose transverse dimension is min. 10 mm
- with an ideally smooth contact surface
- without the slightest air gap between the magnet and steel
- under vertical force direction (90-degree angle)
- at room temperature
Magnet lifting force in use – key factors
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
- Material composition – different alloys attracts identically. High carbon content worsen the interaction with the magnet.
- Plate texture – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces reduce efficiency.
- Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was determined by applying a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate decreases the load capacity.
Safe handling of neodymium magnets
ICD Warning
For implant holders: Powerful magnets disrupt medical devices. Keep at least 30 cm distance or request help to handle the magnets.
Finger safety
Risk of injury: The attraction force is so immense that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Danger to the youngest
These products are not toys. Accidental ingestion of multiple magnets can lead to them connecting inside the digestive tract, which constitutes a direct threat to life and requires urgent medical intervention.
Risk of cracking
Neodymium magnets are ceramic materials, which means they are very brittle. Clashing of two magnets will cause them cracking into shards.
Maximum temperature
Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Respect the power
Handle magnets with awareness. Their immense force can surprise even professionals. Stay alert and do not underestimate their force.
Cards and drives
Avoid bringing magnets close to a purse, computer, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
Metal Allergy
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness occurs, immediately stop working with magnets and wear gloves.
GPS and phone interference
Note: neodymium magnets generate a field that interferes with sensitive sensors. Keep a safe distance from your phone, device, and navigation systems.
Combustion hazard
Dust produced during grinding of magnets is combustible. Do not drill into magnets unless you are an expert.
