Strengths as well as weaknesses of neodymium magnets.
Strengths
- Their magnetic field remains stable, and after around ten years it drops only by ~1% (according to research),
- They feature excellent resistance to magnetism drop due to external magnetic sources,
- Thanks to the reflective finish, the layer of Ni-Cu-Ni, gold-plated, or silver-plated gives an professional appearance,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of custom shaping and optimizing to atypical conditions,
- Wide application in modern technologies – they serve a role in mass storage devices, electric motors, medical equipment, and modern systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Weaknesses
- At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 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 resistant to moisture, in case of application outdoors
- We suggest cover - magnetic holder, due to difficulties in realizing threads inside the magnet and complex forms.
- Potential hazard resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets can be problematic in diagnostics medical when they are in the body.
- With mass production the cost of neodymium magnets is a challenge,
Lifting parameters
Best holding force of the magnet in ideal parameters – what it depends on?
- using a sheet made of high-permeability steel, functioning as a magnetic yoke
- with a cross-section of at least 10 mm
- with an ground touching surface
- with direct contact (without impurities)
- for force acting at a right angle (in the magnet axis)
- at temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of maximum force).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Material type – ideal substrate is high-permeability steel. Hardened steels may attract less.
- Smoothness – full contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
- Heat – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was determined using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet and the plate reduces the load capacity.
Safe handling of NdFeB magnets
Do not drill into magnets
Mechanical processing of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Precision electronics
Remember: neodymium magnets produce a field that confuses sensitive sensors. Keep a separation from your phone, device, and navigation systems.
Respect the power
Handle magnets consciously. Their powerful strength can surprise even professionals. Be vigilant and respect their power.
Adults only
Product intended for adults. Tiny parts can be swallowed, leading to intestinal necrosis. Store out of reach of kids and pets.
Warning for allergy sufferers
A percentage of the population experience a hypersensitivity to nickel, which is the typical protective layer for neodymium magnets. Prolonged contact can result in skin redness. It is best to use safety gloves.
Protect data
Intense magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.
Power loss in heat
Regular neodymium magnets (N-type) lose power when the temperature exceeds 80°C. Damage is permanent.
ICD Warning
Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Crushing force
Big blocks can crush fingers instantly. Do not put your hand betwixt two attracting surfaces.
Fragile material
Watch out for shards. Magnets can explode upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.
