Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (according to literature),
- They are noted for resistance to demagnetization induced by presence of other magnetic fields,
- A magnet with a metallic nickel surface looks better,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Considering the potential of accurate forming and customization to unique needs, magnetic components can be modeled in a wide range of forms and dimensions, which makes them more universal,
- Key role in high-tech industry – they are used in data components, drive modules, medical devices, and multitasking production systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a special holder, which not only protects them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in producing nuts and complicated shapes in magnets, we recommend using a housing - magnetic holder.
- Health risk resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the context of child safety. Furthermore, small components of these products are able to complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Best holding force of the magnet in ideal parameters – what contributes to it?
- on a block made of mild steel, effectively closing the magnetic field
- possessing a massiveness of min. 10 mm to avoid saturation
- characterized by even structure
- with zero gap (no paint)
- during detachment in a direction perpendicular to the mounting surface
- at room temperature
What influences lifting capacity in practice
- Distance – existence of any layer (rust, tape, gap) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel gives the best results. Alloy admixtures decrease magnetic properties and holding force.
- Plate texture – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal weaken the grip.
- Thermal conditions – neodymium magnets 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 was determined by applying a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate reduces the holding force.
Precautions when working with neodymium magnets
Compass and GPS
A strong magnetic field disrupts the functioning of magnetometers in smartphones and navigation systems. Maintain magnets near a device to prevent breaking the sensors.
Fragile material
Despite the nickel coating, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.
Handling guide
Handle magnets consciously. Their powerful strength can surprise even experienced users. Be vigilant and respect their force.
Warning for allergy sufferers
Studies show that nickel (standard magnet coating) is a potent allergen. If your skin reacts to metals, prevent touching magnets with bare hands and choose versions in plastic housing.
Heat warning
Watch the temperature. Heating the magnet above 80 degrees Celsius will ruin its properties and strength.
Threat to electronics
Avoid bringing magnets close to a wallet, laptop, or TV. The magnetism can destroy these devices and erase data from cards.
Swallowing risk
Always keep magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are life-threatening.
Medical interference
Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Pinching danger
Large magnets can smash fingers in a fraction of a second. Do not put your hand between two strong magnets.
Mechanical processing
Drilling and cutting of NdFeB material poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
