Pros as well as cons of neodymium magnets.
Pros
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
- Magnets very well resist against loss of magnetization caused by ambient magnetic noise,
- A magnet with a smooth nickel surface has better aesthetics,
- Magnets have maximum magnetic induction on the outer layer,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures reaching 230°C and above...
- Possibility of custom machining as well as adjusting to individual applications,
- Significant place in advanced technology sectors – they are used in data components, electric motors, medical devices, also industrial machines.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a steel housing, which not only protects them against impacts but also raises their durability
- Neodymium magnets decrease their strength 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 durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- We recommend casing - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complex forms.
- Potential hazard resulting from small fragments of magnets are risky, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products 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
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what affects it?
- on a base made of structural steel, optimally conducting the magnetic flux
- whose transverse dimension equals approx. 10 mm
- with an ideally smooth touching surface
- under conditions of ideal adhesion (metal-to-metal)
- under vertical force direction (90-degree angle)
- in neutral thermal conditions
Impact of factors on magnetic holding capacity in practice
- Gap (between the magnet and the plate), because even a very small distance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to paint, corrosion or dirt).
- Direction of force – maximum parameter is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin plate does not close the flux, causing part of the flux to be wasted into the air.
- Metal type – not every steel reacts the same. High carbon content worsen the interaction with the magnet.
- Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity was determined using a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate lowers the load capacity.
Warnings
Dust explosion hazard
Powder generated during machining of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Magnetic interference
Be aware: rare earth magnets produce a field that confuses sensitive sensors. Keep a safe distance from your mobile, device, and navigation systems.
Skin irritation risks
Medical facts indicate that nickel (the usual finish) is a common allergen. If you have an allergy, refrain from direct skin contact and opt for coated magnets.
Protect data
Avoid bringing magnets close to a wallet, laptop, or TV. The magnetism can destroy these devices and wipe information from cards.
Warning for heart patients
Patients with a ICD must maintain an absolute distance from magnets. The magnetic field can stop the functioning of the life-saving device.
Adults only
Always store magnets away from children. Choking hazard is high, and the consequences of magnets connecting inside the body are tragic.
Handling rules
Use magnets consciously. Their powerful strength can shock even experienced users. Be vigilant and do not underestimate their force.
Heat warning
Control the heat. Heating the magnet to high heat will permanently weaken its magnetic structure and strength.
Bone fractures
Danger of trauma: The pulling power is so immense that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Beware of splinters
NdFeB magnets are ceramic materials, meaning they are prone to chipping. Collision of two magnets leads to them breaking into shards.
