Pros and cons of rare earth magnets.
Advantages
- Their magnetic field remains stable, and after around 10 years it drops only by ~1% (according to research),
- Neodymium magnets prove to be exceptionally resistant to loss of magnetic properties caused by magnetic disturbances,
- The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to look better,
- Neodymium magnets ensure maximum magnetic induction on a small area, which increases force concentration,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to freedom in shaping and the capacity to adapt to individual projects,
- Fundamental importance in modern industrial fields – they are commonly used in HDD drives, drive modules, medical equipment, and other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in small systems
Disadvantages
- At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and 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 stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We suggest a housing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated forms.
- Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Additionally, small elements of these magnets can complicate diagnosis medical when they are in the body.
- With large orders the cost of neodymium magnets is economically unviable,
Pull force analysis
Best holding force of the magnet in ideal parameters – what affects it?
- using a plate made of low-carbon steel, acting as a ideal flux conductor
- whose transverse dimension equals approx. 10 mm
- with an ideally smooth touching surface
- under conditions of no distance (surface-to-surface)
- for force applied at a right angle (pull-off, not shear)
- in stable room temperature
Key elements affecting lifting force
- Distance (betwixt the magnet and the plate), since even a microscopic clearance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Plate material – low-carbon steel attracts best. Higher carbon content lower magnetic properties and lifting capacity.
- Surface quality – the smoother and more polished the surface, the better the adhesion and stronger the hold. Unevenness creates an air distance.
- Heat – neodymium magnets have a sensitivity to temperature. 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 perpendicular detachment force, whereas under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
Safety rules for work with neodymium magnets
Immense force
Before use, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Danger to the youngest
Absolutely keep magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are tragic.
Fire risk
Drilling and cutting of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Protective goggles
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
Serious injuries
Risk of injury: The pulling power is so immense that it can result in hematomas, crushing, and even bone fractures. Use thick gloves.
GPS and phone interference
An intense magnetic field negatively affects the functioning of compasses in phones and GPS navigation. Keep magnets close to a device to prevent damaging the sensors.
Threat to electronics
Data protection: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).
Medical implants
Life threat: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
Maximum temperature
Avoid heat. Neodymium magnets are sensitive to heat. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Skin irritation risks
Studies show that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, avoid touching magnets with bare hands and select versions in plastic housing.
