Strengths and weaknesses of neodymium magnets.
Pros
- They retain attractive force for around ten years – the loss is just ~1% (based on simulations),
- Neodymium magnets are highly resistant to demagnetization caused by external field sources,
- Thanks to the elegant finish, the coating of Ni-Cu-Ni, gold, or silver-plated gives an aesthetic appearance,
- They are known for high magnetic induction at the operating surface, which improves attraction properties,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to versatility in shaping and the capacity to adapt to client solutions,
- Significant place in modern technologies – they serve a role in HDD drives, electric drive systems, advanced medical instruments, as well as multitasking production systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Limited possibility of producing nuts in the magnet and complex forms - preferred is cover - mounting mechanism.
- Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. Furthermore, small elements of these devices can be problematic in diagnostics medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Magnetic strength at its maximum – what affects it?
- with the application of a sheet made of special test steel, ensuring maximum field concentration
- whose transverse dimension is min. 10 mm
- with a surface cleaned and smooth
- with zero gap (without coatings)
- during detachment in a direction vertical to the plane
- in temp. approx. 20°C
Lifting capacity in practice – influencing factors
- Gap (between the magnet and the plate), because even a microscopic distance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to paint, rust or debris).
- Force direction – catalog parameter refers to detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Material type – the best choice is pure iron steel. Cast iron may attract less.
- Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, 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 the force acted perpendicularly, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate decreases the holding force.
Safety rules for work with NdFeB magnets
Electronic hazard
Equipment safety: Strong magnets can damage payment cards and sensitive devices (heart implants, hearing aids, timepieces).
Caution required
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
GPS Danger
An intense magnetic field negatively affects the operation of compasses in phones and GPS navigation. Do not bring magnets close to a device to avoid breaking the sensors.
ICD Warning
Patients with a ICD must maintain an absolute distance from magnets. The magnetic field can interfere with the functioning of the implant.
Fire warning
Drilling and cutting of neodymium magnets carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Avoid contact if allergic
Studies show that nickel (standard magnet coating) is a potent allergen. For allergy sufferers, avoid touching magnets with bare hands or opt for versions in plastic housing.
Heat sensitivity
Do not overheat. Neodymium magnets are susceptible to temperature. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Eye protection
NdFeB magnets are ceramic materials, which means they are very brittle. Clashing of two magnets will cause them shattering into small pieces.
This is not a toy
Adult use only. Small elements pose a choking risk, leading to serious injuries. Store out of reach of kids and pets.
Bodily injuries
Risk of injury: The attraction force is so great that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.
