Pros and cons of neodymium magnets.
Benefits
- They have unchanged lifting capacity, and over nearly ten years their attraction force decreases symbolically – ~1% (according to theory),
- They do not lose their magnetic properties even under external field action,
- In other words, due to the smooth layer of gold, the element is aesthetically pleasing,
- Neodymium magnets deliver maximum magnetic induction on a contact point, which ensures high operational effectiveness,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of precise shaping as well as optimizing to defined needs,
- Significant place in modern industrial fields – they are used in HDD drives, brushless drives, medical equipment, also other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Limited possibility of making threads in the magnet and complex shapes - preferred is cover - magnetic holder.
- Possible danger to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these devices 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
Holding force characteristics
Highest magnetic holding force – what contributes to it?
- with the use of a sheet made of special test steel, guaranteeing maximum field concentration
- whose transverse dimension reaches at least 10 mm
- characterized by lack of roughness
- under conditions of ideal adhesion (surface-to-surface)
- under perpendicular application of breakaway force (90-degree angle)
- at room temperature
Lifting capacity in real conditions – factors
- Distance – existence of any layer (rust, tape, air) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Angle of force application – highest force is available only during perpendicular pulling. The force required to slide of the magnet along the surface is typically many times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Material type – the best choice is high-permeability steel. Stainless steels may generate lower lifting capacity.
- Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Thermal environment – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate decreases the lifting capacity.
Warnings
Keep away from computers
Intense magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Stay away of min. 10 cm.
Avoid contact if allergic
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If redness occurs, cease working with magnets and wear gloves.
Magnet fragility
Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Permanent damage
Keep cool. NdFeB magnets are sensitive to temperature. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).
Danger to pacemakers
Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Precision electronics
Remember: rare earth magnets produce a field that confuses precision electronics. Maintain a safe distance from your phone, tablet, and navigation systems.
Crushing risk
Danger of trauma: The pulling power is so great that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Immense force
Handle magnets with awareness. Their powerful strength can surprise even experienced users. Plan your moves and do not underestimate their force.
Keep away from children
Product intended for adults. Tiny parts pose a choking risk, causing serious injuries. Keep out of reach of kids and pets.
Mechanical processing
Fire warning: Rare earth powder is explosive. Do not process magnets without safety gear as this risks ignition.
