Pros and cons of neodymium magnets.
Benefits
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (based on calculations),
- Neodymium magnets are characterized by highly resistant to magnetic field loss caused by magnetic disturbances,
- Thanks to the shiny finish, the coating of Ni-Cu-Ni, gold-plated, or silver gives an professional appearance,
- Magnets have huge magnetic induction on the outer layer,
- 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...
- Possibility of exact modeling as well as adjusting to complex applications,
- Versatile presence in advanced technology sectors – they are utilized in computer drives, motor assemblies, medical equipment, also modern systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets suffer a drop in force. 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
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We recommend cover - magnetic holder, due to difficulties in producing threads inside the magnet and complex shapes.
- Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, tiny parts of these magnets are able to be problematic in diagnostics medical after entering the body.
- With mass production the cost of neodymium magnets is a challenge,
Pull force analysis
Maximum holding power of the magnet – what it depends on?
- using a base made of high-permeability steel, functioning as a circuit closing element
- possessing a thickness of min. 10 mm to ensure full flux closure
- characterized by lack of roughness
- with total lack of distance (no impurities)
- under perpendicular application of breakaway force (90-degree angle)
- at standard ambient temperature
Key elements affecting lifting force
- Distance – the presence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, 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.
- Steel type – low-carbon steel gives the best results. Higher carbon content lower magnetic permeability and holding force.
- Base smoothness – the more even the surface, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Temperature – heating the magnet causes a temporary drop of force. It is worth remembering the thermal limit for a given model.
Lifting capacity was determined by applying a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate decreases the holding force.
Safe handling of NdFeB magnets
Pacemakers
Life threat: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Demagnetization risk
Keep cool. Neodymium magnets are susceptible to heat. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).
Combustion hazard
Powder produced during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.
Fragile material
Despite metallic appearance, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Crushing risk
Risk of injury: The attraction force is so great that it can result in blood blisters, crushing, and broken bones. Protective gloves are recommended.
Skin irritation risks
Certain individuals suffer from a contact allergy to Ni, which is the common plating for NdFeB magnets. Frequent touching can result in a rash. We strongly advise wear protective gloves.
Safe operation
Handle with care. Neodymium magnets act from a distance and snap with huge force, often faster than you can move away.
Do not give to children
Strictly store magnets away from children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are fatal.
Data carriers
Data protection: Neodymium magnets can damage payment cards and delicate electronics (pacemakers, hearing aids, mechanical watches).
Precision electronics
Be aware: rare earth magnets produce a field that disrupts sensitive sensors. Maintain a safe distance from your mobile, device, and GPS.
