Pros and cons of neodymium magnets.
Advantages
- Their power is durable, and after approximately 10 years it drops only by ~1% (according to research),
- They have excellent resistance to weakening of magnetic properties when exposed to opposing magnetic fields,
- By applying a decorative layer of silver, the element presents an modern look,
- Magnets have very high magnetic induction on the surface,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- In view of the option of accurate forming and customization to specialized requirements, magnetic components can be modeled in a variety of forms and dimensions, which expands the range of possible applications,
- Significant place in advanced technology sectors – they find application in data components, electric motors, medical equipment, as well as modern systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Disadvantages
- Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a special holder, which not only protects them against impacts but also increases their durability
- NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited possibility of creating threads in the magnet and complex shapes - recommended is casing - mounting mechanism.
- Possible danger to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these devices can disrupt the diagnostic process medical in case of swallowing.
- With mass production the cost of neodymium magnets is economically unviable,
Pull force analysis
Detachment force of the magnet in optimal conditions – what affects it?
- using a sheet made of mild steel, serving as a circuit closing element
- whose transverse dimension is min. 10 mm
- with a surface perfectly flat
- under conditions of ideal adhesion (metal-to-metal)
- for force applied at a right angle (pull-off, not shear)
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Air gap (betwixt the magnet and the plate), as even a tiny distance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Direction of force – highest force is obtained only during perpendicular pulling. The shear force of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Steel grade – the best choice is high-permeability steel. Stainless steels may generate lower lifting capacity.
- Surface structure – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Thermal environment – temperature increase causes a temporary drop of force. Check the thermal limit for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate lowers the holding force.
H&S for magnets
Safe operation
Handle magnets with awareness. Their immense force can shock even experienced users. Be vigilant and respect their force.
Adults only
Product intended for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Store out of reach of kids and pets.
Keep away from computers
Device Safety: Strong magnets can damage payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).
Magnets are brittle
Despite the nickel coating, the material is brittle and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.
Threat to navigation
Navigation devices and mobile phones are extremely sensitive to magnetism. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.
Fire risk
Powder produced during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.
ICD Warning
Life threat: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Do not overheat magnets
Control the heat. Heating the magnet to high heat will destroy its properties and pulling force.
Bone fractures
Mind your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Warning for allergy sufferers
A percentage of the population have a hypersensitivity to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact may cause a rash. We strongly advise wear safety gloves.
