Advantages as well as disadvantages of neodymium magnets.
Pros
- They have constant strength, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
- They are noted for resistance to demagnetization induced by presence of other magnetic fields,
- In other words, due to the metallic finish of gold, the element becomes visually attractive,
- Magnetic induction on the top side of the magnet turns out to be impressive,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures reaching 230°C and above...
- Thanks to the possibility of accurate molding and adaptation to individualized requirements, neodymium magnets can be created in a wide range of forms and dimensions, which increases their versatility,
- Versatile presence in innovative solutions – they serve a role in computer drives, electromotive mechanisms, medical equipment, and other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in compact constructions
Cons
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a special holder, which not only protects them against impacts but also raises their durability
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Limited ability of creating threads in the magnet and complicated shapes - preferred is cover - mounting mechanism.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices can be problematic in diagnostics medical after entering the body.
- Due to expensive raw materials, their price is higher than average,
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what it depends on?
- with the application of a yoke made of special test steel, ensuring maximum field concentration
- with a thickness of at least 10 mm
- with a plane cleaned and smooth
- without any clearance between the magnet and steel
- during detachment in a direction vertical to the plane
- in temp. approx. 20°C
Determinants of practical lifting force of a magnet
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Base massiveness – too thin plate does not close the flux, causing part of the power to be lost into the air.
- Steel type – low-carbon steel gives the best results. Alloy admixtures reduce magnetic permeability and holding force.
- Base smoothness – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate decreases the load capacity.
Precautions when working with NdFeB magnets
Handling rules
Before starting, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
Magnets are brittle
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Medical implants
Individuals with a pacemaker should maintain an absolute distance from magnets. The magnetic field can stop the functioning of the implant.
Swallowing risk
These products are not toys. Swallowing multiple magnets can lead to them attracting across intestines, which constitutes a severe health hazard and requires urgent medical intervention.
Bodily injuries
Danger of trauma: The pulling power is so great that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Fire warning
Powder generated during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Magnetic media
Powerful magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.
Sensitization to coating
Certain individuals suffer from a contact allergy to Ni, which is the common plating for NdFeB magnets. Frequent touching can result in an allergic reaction. We suggest use safety gloves.
Permanent damage
Control the heat. Heating the magnet to high heat will permanently weaken its magnetic structure and strength.
Magnetic interference
Navigation devices and mobile phones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can ruin the internal compass in your phone.
