Pros and cons of rare earth magnets.
Advantages
- Their power is durable, and after approximately 10 years it decreases only by ~1% (according to research),
- They retain their magnetic properties even under strong external field,
- A magnet with a shiny nickel surface has better aesthetics,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to flexibility in shaping and the capacity to adapt to complex applications,
- Versatile presence in high-tech industry – they are used in mass storage devices, drive modules, advanced medical instruments, and industrial machines.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Limitations
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a special holder, which not only secures them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and 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 start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Limited ability of producing nuts in the magnet and complicated forms - recommended is cover - mounting mechanism.
- Health risk related to microscopic parts of magnets are risky, if swallowed, which gains importance in the context of child health protection. It is also worth noting that small components 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 magnetic pulling force – what affects it?
- using a base made of low-carbon steel, acting as a circuit closing element
- whose transverse dimension is min. 10 mm
- with an polished contact surface
- without the slightest insulating layer between the magnet and steel
- during detachment in a direction perpendicular to the plane
- in stable room temperature
Practical aspects of lifting capacity – factors
- Distance – existence of any layer (rust, tape, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Steel type – mild steel gives the best results. Alloy steels lower magnetic properties and lifting capacity.
- Surface structure – the smoother and more polished the plate, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a slight gap between the magnet and the plate reduces the load capacity.
Safety rules for work with NdFeB magnets
Heat sensitivity
Do not overheat. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, inquire about HT versions (H, SH, UH).
Flammability
Combustion risk: Neodymium dust is explosive. Avoid machining magnets in home conditions as this may cause fire.
Pinching danger
Danger of trauma: The pulling power is so great that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.
Protect data
Do not bring magnets close to a purse, laptop, or TV. The magnetic field can destroy these devices and wipe information from cards.
Phone sensors
A powerful magnetic field interferes with the functioning of magnetometers in phones and GPS navigation. Do not bring magnets close to a device to avoid damaging the sensors.
Beware of splinters
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
Keep away from children
Neodymium magnets are not toys. Accidental ingestion of several magnets can lead to them pinching intestinal walls, which poses a critical condition and requires urgent medical intervention.
Allergy Warning
Medical facts indicate that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, avoid direct skin contact or opt for versions in plastic housing.
ICD Warning
People with a heart stimulator should keep an safe separation from magnets. The magnetism can stop the functioning of the implant.
Handling guide
Be careful. Neodymium magnets attract from a long distance and snap with massive power, often quicker than you can react.
