Strengths as well as weaknesses of Nd2Fe14B magnets.
Advantages
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- They do not lose their magnetic properties even under close interference source,
- The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnetic induction on the top side of the magnet turns out to be exceptional,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Due to the option of precise molding and customization to specialized requirements, neodymium magnets can be modeled in a variety of shapes and sizes, which amplifies use scope,
- Wide application in modern industrial fields – they are utilized in mass storage devices, electric drive systems, advanced medical instruments, and complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Disadvantages
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- We suggest casing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complex forms.
- Health risk to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small elements of these products are able to complicate diagnosis medical in case of swallowing.
- With mass production the cost of neodymium magnets is economically unviable,
Holding force characteristics
Maximum magnetic pulling force – what contributes to it?
- with the use of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- whose thickness reaches at least 10 mm
- with an ground contact surface
- under conditions of ideal adhesion (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- in neutral thermal conditions
Practical lifting capacity: influencing factors
- Gap between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Material composition – not every steel reacts the same. High carbon content weaken the interaction with the magnet.
- Smoothness – full contact is possible only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet’s surface and the plate reduces the holding force.
Warnings
Power loss in heat
Do not overheat. NdFeB magnets are sensitive to heat. If you require operation above 80°C, look for HT versions (H, SH, UH).
Adults only
Only for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Keep out of reach of children and animals.
Handling guide
Handle with care. Rare earth magnets act from a distance and snap with huge force, often quicker than you can react.
Keep away from electronics
Navigation devices and smartphones are extremely susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Finger safety
Large magnets can crush fingers instantly. Under no circumstances put your hand betwixt two strong magnets.
Sensitization to coating
Some people experience a contact allergy to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact may cause a rash. We strongly advise use protective gloves.
Health Danger
Warning for patients: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or request help to handle the magnets.
Fire risk
Powder created during grinding of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Risk of cracking
Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Safe distance
Equipment safety: Neodymium magnets can damage data carriers and sensitive devices (heart implants, hearing aids, timepieces).
