Pros as well as cons of rare earth magnets.
Benefits
- They have unchanged lifting capacity, and over nearly 10 years their performance decreases symbolically – ~1% (according to theory),
- They retain their magnetic properties even under strong external field,
- In other words, due to the reflective finish of nickel, the element becomes visually attractive,
- Neodymium magnets generate maximum magnetic induction on a contact point, which allows for strong attraction,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of precise shaping and adapting to specific needs,
- Wide application in advanced technology sectors – they are commonly used in data components, electric motors, diagnostic systems, and technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- At very strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We suggest casing - magnetic mount, due to difficulties in realizing nuts inside the magnet and complicated forms.
- Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. It is also worth noting that small components of these products can complicate diagnosis medical when they are in the body.
- With large orders the cost of neodymium magnets is economically unviable,
Pull force analysis
Best holding force of the magnet in ideal parameters – what affects it?
- using a base made of high-permeability steel, acting as a ideal flux conductor
- possessing a thickness of minimum 10 mm to avoid saturation
- characterized by lack of roughness
- under conditions of no distance (metal-to-metal)
- under vertical force direction (90-degree angle)
- at temperature room level
Determinants of lifting force in real conditions
- Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Angle of force application – maximum parameter is obtained only during perpendicular pulling. The shear force of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Chemical composition of the base – mild steel gives the best results. Higher carbon content reduce magnetic properties and lifting capacity.
- Surface condition – smooth surfaces ensure maximum contact, which improves force. Rough surfaces weaken the grip.
- Thermal environment – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was measured by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under shearing force the holding force is lower. In addition, even a slight gap between the magnet and the plate decreases the load capacity.
Safe handling of NdFeB magnets
Keep away from electronics
Navigation devices and smartphones are highly sensitive to magnetic fields. Close proximity with a strong magnet can permanently damage the sensors in your phone.
Do not underestimate power
Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Be predictive.
Keep away from computers
Avoid bringing magnets close to a purse, computer, or screen. The magnetism can destroy these devices and erase data from cards.
Allergic reactions
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness appears, immediately stop working with magnets and wear gloves.
Medical implants
People with a pacemaker should maintain an large gap from magnets. The magnetic field can stop the functioning of the life-saving device.
Permanent damage
Keep cool. Neodymium magnets are susceptible to temperature. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Serious injuries
Danger of trauma: The pulling power is so great that it can cause hematomas, pinching, and even bone fractures. Use thick gloves.
Machining danger
Machining of neodymium magnets carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Magnets are brittle
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
No play value
NdFeB magnets are not suitable for play. Accidental ingestion of a few magnets can lead to them pinching intestinal walls, which poses a severe health hazard and requires immediate surgery.
