Pros as well as cons of neodymium magnets.
Strengths
- They retain full power for nearly 10 years – the loss is just ~1% (in theory),
- Neodymium magnets are distinguished by highly resistant to magnetic field loss caused by external magnetic fields,
- By applying a shiny coating of silver, the element presents an elegant look,
- The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Thanks to the option of free shaping and adaptation to custom projects, magnetic components can be modeled in a wide range of shapes and sizes, which makes them more universal,
- Versatile presence in modern technologies – they are used in mass storage devices, electromotive mechanisms, precision medical tools, also complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases 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, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We recommend cover - magnetic holder, due to difficulties in producing nuts inside the magnet and complicated forms.
- Possible danger to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child safety. Furthermore, tiny parts of these magnets can complicate diagnosis medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum lifting capacity of the magnet – what it depends on?
- on a base made of mild steel, optimally conducting the magnetic flux
- with a cross-section of at least 10 mm
- with a plane free of scratches
- under conditions of no distance (surface-to-surface)
- during pulling in a direction perpendicular to the plane
- in temp. approx. 20°C
Determinants of lifting force in real conditions
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Angle of force application – highest force is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Plate material – low-carbon steel gives the best results. Higher carbon content lower magnetic properties and lifting capacity.
- Surface structure – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Temperature influence – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.
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 load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet and the plate reduces the holding force.
Precautions when working with neodymium magnets
GPS and phone interference
Navigation devices and mobile phones are highly sensitive to magnetism. Direct contact with a strong magnet can ruin the sensors in your phone.
Dust explosion hazard
Powder generated during cutting of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
Do not give to children
Always keep magnets away from children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are tragic.
Implant safety
Individuals with a ICD have to maintain an large gap from magnets. The magnetism can interfere with the operation of the life-saving device.
Eye protection
Beware of splinters. Magnets can explode upon violent connection, ejecting sharp fragments into the air. We recommend safety glasses.
Power loss in heat
Control the heat. Exposing the magnet to high heat will destroy its magnetic structure and pulling force.
Handling rules
Use magnets consciously. Their immense force can surprise even professionals. Stay alert and do not underestimate their force.
Allergic reactions
Studies show that nickel (standard magnet coating) is a strong allergen. For allergy sufferers, prevent direct skin contact or choose coated magnets.
Crushing force
Pinching hazard: The pulling power is so immense that it can cause blood blisters, pinching, and broken bones. Protective gloves are recommended.
Cards and drives
Equipment safety: Neodymium magnets can ruin payment cards and delicate electronics (heart implants, hearing aids, mechanical watches).
