Strengths and weaknesses of Nd2Fe14B magnets.
Strengths
- Their power remains stable, and after around ten years it decreases only by ~1% (according to research),
- Magnets effectively resist against demagnetization caused by ambient magnetic noise,
- In other words, due to the shiny finish of nickel, the element becomes visually attractive,
- The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
- 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 freedom in designing and the capacity to customize to individual projects,
- Significant place in innovative solutions – they find application in data components, electric motors, diagnostic systems, and multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Limitations
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also raises their durability
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend 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 stable to moisture, in case of application outdoors
- Due to limitations in producing threads and complex shapes in magnets, we propose using casing - magnetic mount.
- Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these products are able to complicate diagnosis medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Best holding force of the magnet in ideal parameters – what it depends on?
- using a plate made of mild steel, acting as a magnetic yoke
- with a thickness minimum 10 mm
- characterized by even structure
- without the slightest air gap between the magnet and steel
- under vertical force vector (90-degree angle)
- in neutral thermal conditions
Magnet lifting force in use – key factors
- Air gap (between the magnet and the plate), since even a tiny clearance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Force direction – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (typically 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).
- Chemical composition of the base – low-carbon steel attracts best. Alloy steels decrease magnetic permeability and lifting capacity.
- Surface condition – ground elements ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.
H&S for magnets
Risk of cracking
Despite metallic appearance, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Pinching danger
Large magnets can smash fingers in a fraction of a second. Do not place your hand between two strong magnets.
GPS and phone interference
An intense magnetic field interferes with the operation of magnetometers in phones and GPS navigation. Keep magnets near a smartphone to avoid breaking the sensors.
Allergy Warning
Studies show that the nickel plating (standard magnet coating) is a common allergen. If your skin reacts to metals, prevent touching magnets with bare hands or opt for coated magnets.
Handling rules
Use magnets with awareness. Their powerful strength can surprise even experienced users. Plan your moves and do not underestimate their power.
Swallowing risk
Product intended for adults. Tiny parts pose a choking risk, leading to intestinal necrosis. Keep away from children and animals.
Implant safety
Warning for patients: Powerful magnets affect electronics. Keep at least 30 cm distance or ask another person to handle the magnets.
Fire risk
Dust generated during grinding of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Operating temperature
Monitor thermal conditions. Heating the magnet to high heat will destroy its properties and strength.
Cards and drives
Do not bring magnets near a purse, laptop, or TV. The magnetic field can permanently damage these devices and erase data from cards.
