Advantages as well as disadvantages of neodymium magnets.
Strengths
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
- Neodymium magnets are exceptionally resistant to magnetic field loss caused by external magnetic fields,
- In other words, due to the smooth surface of silver, the element gains visual value,
- The surface of neodymium magnets generates a unique magnetic field – this is a distinguishing feature,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Considering the potential of precise molding and adaptation to unique requirements, magnetic components can be manufactured in a broad palette of geometric configurations, which expands the range of possible applications,
- Significant place in innovative solutions – they serve a role in magnetic memories, motor assemblies, precision medical tools, also multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Cons
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. 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 strength. Often, when the temperature exceeds 80°C, their strength 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
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in creating threads and complex shapes in magnets, we propose using cover - magnetic mount.
- Health risk resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. It is also worth noting that small components of these magnets can be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum magnetic pulling force – what contributes to it?
- on a block made of structural steel, effectively closing the magnetic flux
- with a thickness minimum 10 mm
- with a surface cleaned and smooth
- without any clearance between the magnet and steel
- under vertical application of breakaway force (90-degree angle)
- at temperature room level
Practical lifting capacity: influencing factors
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Steel thickness – too thin steel causes magnetic saturation, causing part of the power to be wasted into the air.
- Chemical composition of the base – low-carbon steel attracts best. Alloy admixtures lower magnetic properties and lifting capacity.
- Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal weaken the grip.
- Thermal environment – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.
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 load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet and the plate decreases the holding force.
Safe handling of neodymium magnets
Data carriers
Avoid bringing magnets near a wallet, computer, or screen. The magnetic field can destroy these devices and erase data from cards.
Respect the power
Handle with care. Rare earth magnets attract from a long distance and snap with huge force, often faster than you can move away.
Permanent damage
Do not overheat. Neodymium magnets are sensitive to temperature. If you need operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Phone sensors
A strong magnetic field interferes with the operation of compasses in smartphones and GPS navigation. Do not bring magnets close to a smartphone to avoid damaging the sensors.
Shattering risk
Neodymium magnets are sintered ceramics, meaning they are very brittle. Clashing of two magnets leads to them shattering into small pieces.
Life threat
Individuals with a ICD have to maintain an large gap from magnets. The magnetism can stop the operation of the life-saving device.
Fire warning
Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
Adults only
Neodymium magnets are not suitable for play. Swallowing several magnets may result in them connecting inside the digestive tract, which constitutes a severe health hazard and requires immediate surgery.
Bodily injuries
Danger of trauma: The attraction force is so immense that it can result in blood blisters, crushing, and even bone fractures. Protective gloves are recommended.
Metal Allergy
Studies show that the nickel plating (the usual finish) is a strong allergen. For allergy sufferers, prevent direct skin contact and select coated magnets.
