Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (in laboratory conditions),
- They maintain their magnetic properties even under external field action,
- The use of an metallic layer of noble metals (nickel, gold, silver) causes the element to look better,
- The surface of neodymium magnets generates a strong magnetic field – this is one of their assets,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to freedom in forming and the ability to customize to individual projects,
- Wide application in future technologies – they are commonly used in mass storage devices, electric drive systems, medical equipment, as well as modern systems.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited possibility of producing threads in the magnet and complicated shapes - recommended is cover - mounting mechanism.
- Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these products can disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what affects it?
- on a base made of structural steel, effectively closing the magnetic flux
- with a thickness minimum 10 mm
- with a plane free of scratches
- without any insulating layer between the magnet and steel
- during detachment in a direction perpendicular to the plane
- at ambient temperature approx. 20 degrees Celsius
What influences lifting capacity in practice
- Gap (betwixt the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to varnish, corrosion or debris).
- Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Material composition – not every steel reacts the same. Alloy additives worsen the interaction with the magnet.
- Surface condition – smooth surfaces ensure maximum contact, which increases force. Uneven metal weaken the grip.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate lowers the holding force.
H&S for magnets
Allergy Warning
A percentage of the population experience a hypersensitivity to nickel, which is the typical protective layer for neodymium magnets. Extended handling may cause a rash. We strongly advise wear protective gloves.
Do not overheat magnets
Watch the temperature. Exposing the magnet to high heat will destroy its magnetic structure and pulling force.
Finger safety
Mind your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Be careful!
Precision electronics
A strong magnetic field disrupts the operation of magnetometers in phones and GPS navigation. Keep magnets near a smartphone to avoid damaging the sensors.
Shattering risk
NdFeB magnets are ceramic materials, meaning they are fragile like glass. Clashing of two magnets will cause them cracking into small pieces.
Mechanical processing
Fire hazard: Neodymium dust is highly flammable. Do not process magnets in home conditions as this may cause fire.
Warning for heart patients
People with a heart stimulator must maintain an safe separation from magnets. The magnetic field can interfere with the operation of the life-saving device.
This is not a toy
Only for adults. Tiny parts can be swallowed, causing serious injuries. Keep out of reach of kids and pets.
Data carriers
Data protection: Strong magnets can ruin payment cards and delicate electronics (heart implants, medical aids, mechanical watches).
Do not underestimate power
Handle magnets consciously. Their huge power can surprise even professionals. Plan your moves and do not underestimate their force.
