Strengths as well as weaknesses of rare earth magnets.
Pros
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (in laboratory conditions),
- They maintain their magnetic properties even under external field action,
- Thanks to the elegant finish, the plating of Ni-Cu-Ni, gold, or silver-plated gives an elegant appearance,
- Neodymium magnets deliver maximum magnetic induction on a small surface, which allows for strong attraction,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures approaching 230°C and above...
- Possibility of precise forming and adapting to individual applications,
- Wide application in future technologies – they find application in HDD drives, electromotive mechanisms, medical devices, and complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in realizing nuts and complicated forms in magnets, we propose using a housing - magnetic mechanism.
- Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these magnets can be problematic in diagnostics medical when they are in the body.
- Due to expensive raw materials, their price is relatively high,
Lifting parameters
Magnetic strength at its maximum – what affects it?
- on a block made of structural steel, perfectly concentrating the magnetic field
- with a thickness minimum 10 mm
- with an ideally smooth touching surface
- without the slightest clearance between the magnet and steel
- during pulling in a direction perpendicular to the plane
- at room temperature
Lifting capacity in real conditions – factors
- Clearance – the presence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Material type – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
- Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Thermal conditions – 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 testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, however under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance between the magnet and the plate reduces the holding force.
H&S for magnets
Permanent damage
Do not overheat. Neodymium magnets are susceptible to heat. If you need operation above 80°C, inquire about HT versions (H, SH, UH).
Fragile material
Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Crushing force
Danger of trauma: The attraction force is so great that it can result in blood blisters, crushing, and even bone fractures. Use thick gloves.
Safe distance
Powerful magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.
Avoid contact if allergic
Allergy Notice: The nickel-copper-nickel coating contains nickel. If skin irritation happens, immediately stop handling magnets and wear gloves.
Powerful field
Use magnets with awareness. Their powerful strength can shock even professionals. Be vigilant and respect their force.
GPS and phone interference
Be aware: neodymium magnets generate a field that interferes with sensitive sensors. Maintain a separation from your phone, tablet, and GPS.
This is not a toy
These products are not intended for children. Eating a few magnets may result in them pinching intestinal walls, which poses a critical condition and necessitates urgent medical intervention.
Dust is flammable
Drilling and cutting of NdFeB material carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Danger to pacemakers
For implant holders: Powerful magnets disrupt electronics. Maintain minimum 30 cm distance or request help to handle the magnets.
