Pros and cons of Nd2Fe14B magnets.
Strengths
- They have unchanged lifting capacity, and over around ten years their performance decreases symbolically – ~1% (according to theory),
- They are extremely resistant to demagnetization induced by external magnetic fields,
- A magnet with a smooth silver surface has an effective appearance,
- Magnetic induction on the working part of the magnet remains strong,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- In view of the possibility of flexible shaping and adaptation to individualized needs, NdFeB magnets can be created in a broad palette of geometric configurations, which makes them more universal,
- Key role in innovative solutions – they serve a role in magnetic memories, drive modules, precision medical tools, also multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in small systems
Disadvantages
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Limited possibility of producing nuts in the magnet and complex forms - preferred is cover - magnet mounting.
- Potential hazard resulting from small fragments of magnets are risky, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, tiny parts of these products can disrupt the diagnostic process medical after entering the body.
- Due to neodymium price, their price is relatively high,
Pull force analysis
Highest magnetic holding force – what it depends on?
- using a base made of high-permeability steel, functioning as a magnetic yoke
- possessing a thickness of minimum 10 mm to ensure full flux closure
- with a surface perfectly flat
- with direct contact (no coatings)
- for force acting at a right angle (pull-off, not shear)
- at standard ambient temperature
Practical aspects of lifting capacity – factors
- Clearance – the presence of any layer (rust, tape, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Plate material – mild steel attracts best. Alloy admixtures decrease magnetic properties and lifting capacity.
- Surface structure – the more even the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Thermal environment – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.
Precautions when working with neodymium magnets
Swallowing risk
NdFeB magnets are not suitable for play. Swallowing a few magnets can lead to them connecting inside the digestive tract, which constitutes a critical condition and necessitates urgent medical intervention.
Nickel coating and allergies
It is widely known that nickel (the usual finish) is a strong allergen. For allergy sufferers, refrain from direct skin contact and opt for encased magnets.
Handling guide
Handle with care. Rare earth magnets attract from a long distance and connect with massive power, often quicker than you can react.
Physical harm
Pinching hazard: The attraction force is so great that it can cause blood blisters, crushing, and broken bones. Use thick gloves.
Do not drill into magnets
Drilling and cutting of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Eye protection
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.
Demagnetization risk
Keep cool. NdFeB magnets are sensitive to heat. If you need operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Implant safety
Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
GPS and phone interference
A powerful magnetic field disrupts the functioning of compasses in smartphones and GPS navigation. Keep magnets close to a device to prevent damaging the sensors.
Threat to electronics
Do not bring magnets close to a purse, computer, or TV. The magnetism can destroy these devices and wipe information from cards.
