Advantages as well as disadvantages of Nd2Fe14B magnets.
Benefits
- Their power is durable, and after approximately 10 years it decreases only by ~1% (according to research),
- Magnets very well protect themselves against loss of magnetization caused by ambient magnetic noise,
- Thanks to the smooth finish, the surface of nickel, gold, or silver-plated gives an professional appearance,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
- 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...
- Possibility of detailed machining and optimizing to precise conditions,
- Versatile presence in innovative solutions – they are utilized in mass storage devices, motor assemblies, medical equipment, also multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Limitations
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- Neodymium magnets lose their power 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 stability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Due to limitations in producing nuts and complex forms in magnets, we propose using a housing - magnetic mechanism.
- Health risk resulting from small fragments of magnets are risky, if swallowed, which is particularly important in the context of child safety. Furthermore, small elements of these products are able to be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Detachment force of the magnet in optimal conditions – what it depends on?
- using a plate made of mild steel, serving as a ideal flux conductor
- with a cross-section no less than 10 mm
- characterized by even structure
- under conditions of ideal adhesion (metal-to-metal)
- under axial application of breakaway force (90-degree angle)
- in stable room temperature
Impact of factors on magnetic holding capacity in practice
- Distance – the presence of any layer (rust, dirt, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Load vector – highest force is available only during perpendicular pulling. The force required to slide of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Material type – ideal substrate is high-permeability steel. Hardened steels may have worse magnetic properties.
- Surface structure – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was measured by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
Precautions when working with neodymium magnets
Magnetic media
Avoid bringing magnets close to a purse, laptop, or screen. The magnetic field can destroy these devices and erase data from cards.
Sensitization to coating
Certain individuals have a hypersensitivity to Ni, which is the typical protective layer for NdFeB magnets. Frequent touching might lead to an allergic reaction. We recommend use safety gloves.
Do not give to children
Always keep magnets away from children. Choking hazard is significant, and the effects of magnets connecting inside the body are tragic.
Threat to navigation
An intense magnetic field disrupts the operation of magnetometers in smartphones and navigation systems. Do not bring magnets close to a device to avoid breaking the sensors.
Risk of cracking
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Life threat
Individuals with a heart stimulator must maintain an large gap from magnets. The magnetism can interfere with the functioning of the implant.
Heat warning
Regular neodymium magnets (grade N) lose power when the temperature surpasses 80°C. The loss of strength is permanent.
Handling guide
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Bone fractures
Large magnets can crush fingers instantly. Never put your hand between two strong magnets.
Flammability
Drilling and cutting of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
