Other offers
Strengths as well as weaknesses of neodymium magnets.
Pros
- They have stable power, and over nearly ten years their attraction force decreases symbolically – ~1% (according to theory),
- They retain their magnetic properties even under external field action,
- A magnet with a shiny nickel surface has better aesthetics,
- They feature high magnetic induction at the operating surface, making them more effective,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Considering the possibility of accurate shaping and adaptation to individualized projects, magnetic components can be modeled in a wide range of shapes and sizes, which increases their versatility,
- Universal use in modern technologies – they are used in computer drives, electric drive systems, medical devices, also modern systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- 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 and 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 rust. Therefore during using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in realizing nuts and complicated shapes in magnets, we recommend using a housing - magnetic mechanism.
- Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- 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 contributes to it?
- on a base made of mild steel, optimally conducting the magnetic flux
- possessing a massiveness of minimum 10 mm to avoid saturation
- with a surface perfectly flat
- without the slightest clearance between the magnet and steel
- under perpendicular force direction (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
What influences lifting capacity in practice
- Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Plate material – mild steel gives the best results. Alloy admixtures decrease magnetic permeability and holding force.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases field saturation. Uneven metal weaken the grip.
- Temperature – heating the magnet 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 suitable thickness, under perpendicular forces, whereas under parallel forces the holding force is lower. Moreover, even a small distance between the magnet and the plate lowers the holding force.
Warnings
Danger to pacemakers
Individuals with a ICD must maintain an safe separation from magnets. The magnetic field can interfere with the functioning of the implant.
Bodily injuries
Danger of trauma: The attraction force is so immense that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Electronic devices
Intense magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.
Power loss in heat
Monitor thermal conditions. Exposing the magnet to high heat will permanently weaken its magnetic structure and strength.
Beware of splinters
Watch out for shards. Magnets can explode upon violent connection, ejecting shards into the air. We recommend safety glasses.
Keep away from electronics
An intense magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Maintain magnets close to a smartphone to prevent damaging the sensors.
Respect the power
Handle with care. Rare earth magnets attract from a distance and snap with huge force, often faster than you can react.
Dust explosion hazard
Powder generated during cutting of magnets is flammable. Avoid drilling into magnets unless you are an expert.
Metal Allergy
Studies show that nickel (the usual finish) is a strong allergen. If you have an allergy, avoid touching magnets with bare hands or choose encased magnets.
This is not a toy
Neodymium magnets are not suitable for play. Accidental ingestion of several magnets can lead to them connecting inside the digestive tract, which poses a severe health hazard and requires urgent medical intervention.
