Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- They retain full power for nearly 10 years – the drop is just ~1% (according to analyses),
- Magnets very well resist against loss of magnetization caused by foreign field sources,
- In other words, due to the shiny finish of silver, the element is aesthetically pleasing,
- Magnetic induction on the working layer of the magnet turns out to be maximum,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to versatility in constructing and the ability to customize to unusual requirements,
- Universal use in electronics industry – they are utilized in magnetic memories, electric motors, precision medical tools, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in compact constructions
Cons
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- Due to limitations in realizing threads and complicated shapes in magnets, we recommend using a housing - magnetic mount.
- Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. Additionally, small elements of these products are able to disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum holding power of the magnet – what affects it?
- on a plate made of mild steel, perfectly concentrating the magnetic field
- with a thickness of at least 10 mm
- with an ground contact surface
- with zero gap (no impurities)
- under vertical application of breakaway force (90-degree angle)
- at temperature approx. 20 degrees Celsius
Magnet lifting force in use – key factors
- Distance – the presence of foreign body (paint, dirt, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Material type – ideal substrate is pure iron steel. Hardened steels may have worse magnetic properties.
- Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under shearing force the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
Precautions when working with NdFeB magnets
Avoid contact if allergic
A percentage of the population suffer from a hypersensitivity to Ni, which is the common plating for NdFeB magnets. Extended handling may cause an allergic reaction. It is best to use safety gloves.
This is not a toy
Only for adults. Tiny parts can be swallowed, causing severe trauma. Keep away from children and animals.
Danger to pacemakers
Individuals with a heart stimulator have to maintain an absolute distance from magnets. The magnetism can interfere with the functioning of the life-saving device.
Shattering risk
Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Powerful field
Be careful. Rare earth magnets attract from a long distance and connect with huge force, often quicker than you can react.
Operating temperature
Keep cool. NdFeB magnets are susceptible to heat. If you need resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Electronic hazard
Powerful magnetic fields can erase data on credit cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Fire risk
Dust produced during grinding of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
GPS and phone interference
An intense magnetic field interferes with the operation of compasses in phones and GPS navigation. Do not bring magnets close to a device to avoid breaking the sensors.
Crushing force
Large magnets can smash fingers instantly. Under no circumstances put your hand betwixt two strong magnets.
