Pros and cons of neodymium magnets.
Strengths
- They have unchanged lifting capacity, and over more than ten years their attraction force decreases symbolically – ~1% (in testing),
- They have excellent resistance to magnetic field loss when exposed to opposing magnetic fields,
- Thanks to the metallic finish, the coating of nickel, gold, or silver gives an modern appearance,
- Magnets exhibit huge magnetic induction on the active area,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Considering the ability of flexible forming and adaptation to individualized needs, neodymium magnets can be produced in a broad palette of forms and dimensions, which increases their versatility,
- Fundamental importance in electronics industry – they are utilized in data components, drive modules, precision medical tools, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in compact constructions
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a special holder, which not only protects them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as 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 - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We suggest a housing - magnetic mount, due to difficulties in creating nuts inside the magnet and complex forms.
- Possible danger related to microscopic parts of magnets can be dangerous, if swallowed, which becomes key in the context of child health protection. Furthermore, tiny parts of these magnets can disrupt the diagnostic process medical after entering the body.
- Due to complex production process, their price exceeds standard values,
Lifting parameters
Best holding force of the magnet in ideal parameters – what affects it?
- on a plate made of mild steel, effectively closing the magnetic field
- with a cross-section no less than 10 mm
- with a surface cleaned and smooth
- with total lack of distance (no paint)
- during pulling in a direction perpendicular to the mounting surface
- in neutral thermal conditions
Magnet lifting force in use – key factors
- Distance (between the magnet and the plate), because even a microscopic clearance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Material composition – not every steel attracts identically. High carbon content weaken the attraction effect.
- Smoothness – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity was assessed using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
Precautions when working with neodymium magnets
Fire warning
Dust created during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Thermal limits
Control the heat. Heating the magnet to high heat will destroy its properties and pulling force.
Handling rules
Before use, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Warning for heart patients
Patients with a ICD should maintain an absolute distance from magnets. The magnetic field can stop the functioning of the implant.
Finger safety
Mind your fingers. Two large magnets will join instantly with a force of massive weight, destroying everything in their path. Exercise extreme caution!
Keep away from electronics
Note: rare earth magnets generate a field that disrupts sensitive sensors. Keep a separation from your mobile, device, and GPS.
Product not for children
Strictly store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are very dangerous.
Fragile material
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching shards into the air. Wear goggles.
Cards and drives
Device Safety: Strong magnets can ruin data carriers and sensitive devices (pacemakers, medical aids, mechanical watches).
Allergy Warning
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, immediately stop handling magnets and wear gloves.
