Advantages as well as disadvantages of Nd2Fe14B magnets.
Strengths
- They retain magnetic properties for nearly ten years – the loss is just ~1% (according to analyses),
- Magnets very well defend themselves against demagnetization caused by foreign field sources,
- A magnet with a smooth silver surface has better aesthetics,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Considering the potential of flexible molding and customization to specialized solutions, magnetic components can be modeled in a variety of geometric configurations, which increases their versatility,
- Huge importance in innovative solutions – they serve a role in hard drives, brushless drives, medical equipment, as well as multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in compact constructions
Limitations
- At very strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as 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 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. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Limited possibility of making threads in the magnet and complicated shapes - preferred is a housing - magnet mounting.
- Possible danger resulting from small fragments of magnets are risky, if swallowed, which gains importance in the context of child safety. Additionally, tiny parts of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum lifting force for a neodymium magnet – what contributes to it?
- with the contact of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- with a cross-section no less than 10 mm
- with an ground touching surface
- under conditions of ideal adhesion (metal-to-metal)
- under vertical application of breakaway force (90-degree angle)
- at temperature approx. 20 degrees Celsius
Practical lifting capacity: influencing factors
- Distance – the presence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of maximum force).
- Steel thickness – insufficiently thick sheet causes magnetic saturation, causing part of the flux to be wasted into the air.
- Material composition – not every steel reacts the same. High carbon content worsen the attraction effect.
- Base smoothness – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was determined using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate lowers the load capacity.
Safety rules for work with neodymium magnets
Mechanical processing
Mechanical processing of NdFeB material carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Metal Allergy
Nickel alert: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, immediately stop working with magnets and wear gloves.
Handling guide
Be careful. Rare earth magnets act from a long distance and connect with massive power, often quicker than you can react.
Magnets are brittle
Beware of splinters. Magnets can explode upon uncontrolled impact, launching shards into the air. We recommend safety glasses.
Demagnetization risk
Regular neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. This process is irreversible.
Crushing risk
Large magnets can smash fingers in a fraction of a second. Never put your hand between two attracting surfaces.
ICD Warning
Warning for patients: Powerful magnets affect medical devices. Maintain minimum 30 cm distance or ask another person to handle the magnets.
Compass and GPS
Remember: neodymium magnets produce a field that interferes with sensitive sensors. Keep a separation from your phone, device, and GPS.
Cards and drives
Data protection: Strong magnets can ruin payment cards and sensitive devices (pacemakers, medical aids, mechanical watches).
This is not a toy
Neodymium magnets are not suitable for play. Swallowing a few magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and requires urgent medical intervention.
