Pros as well as cons of rare earth magnets.
Strengths
- They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (according to literature),
- They are extremely resistant to demagnetization induced by external field influence,
- The use of an elegant layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- They are known for high magnetic induction at the operating surface, which increases their power,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
- Thanks to freedom in constructing and the capacity to modify to individual projects,
- Key role in high-tech industry – they are used in data components, electric drive systems, medical equipment, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in compact constructions
Limitations
- To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We suggest casing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complicated shapes.
- Health risk related to microscopic parts of magnets are risky, if swallowed, which becomes key in the context of child safety. Furthermore, small elements of these magnets are able to complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what it depends on?
- on a plate made of mild steel, effectively closing the magnetic field
- whose thickness is min. 10 mm
- with an ideally smooth touching surface
- without the slightest insulating layer between the magnet and steel
- under vertical force direction (90-degree angle)
- at ambient temperature room level
Practical aspects of lifting capacity – factors
- Clearance – the presence of foreign body (rust, tape, air) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Base massiveness – too thin plate does not close the flux, causing part of the power to be escaped into the air.
- Chemical composition of the base – low-carbon steel attracts best. Alloy steels decrease magnetic properties and holding force.
- Surface quality – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Thermal environment – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate lowers the load capacity.
Safety rules for work with neodymium magnets
Protect data
Do not bring magnets close to a wallet, computer, or TV. The magnetism can destroy these devices and wipe information from cards.
Danger to pacemakers
People with a heart stimulator have to maintain an large gap from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Conscious usage
Be careful. Neodymium magnets attract from a distance and connect with massive power, often quicker than you can move away.
GPS Danger
A powerful magnetic field negatively affects the operation of magnetometers in smartphones and GPS navigation. Do not bring magnets near a smartphone to avoid damaging the sensors.
Avoid contact if allergic
Studies show that the nickel plating (standard magnet coating) is a common allergen. For allergy sufferers, avoid touching magnets with bare hands or select versions in plastic housing.
Protective goggles
Watch out for shards. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Wear goggles.
Dust is flammable
Mechanical processing of neodymium magnets poses a fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Do not give to children
Product intended for adults. Tiny parts pose a choking risk, leading to severe trauma. Store away from kids and pets.
Physical harm
Risk of injury: The attraction force is so great that it can cause hematomas, pinching, and broken bones. Use thick gloves.
Do not overheat magnets
Do not overheat. NdFeB magnets are susceptible to heat. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
