Strengths as well as weaknesses of neodymium magnets.
Benefits
- They retain magnetic properties for around ten years – the loss is just ~1% (based on simulations),
- Magnets effectively defend themselves against demagnetization caused by ambient magnetic noise,
- The use of an metallic layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Neodymium magnets achieve maximum magnetic induction on a small area, which allows for strong attraction,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Considering the ability of precise shaping and adaptation to specialized solutions, magnetic components can be produced in a variety of geometric configurations, which makes them more universal,
- Huge importance in future technologies – they are used in computer drives, brushless drives, medical equipment, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in miniature devices
Cons
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power 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 start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Limited possibility of making nuts in the magnet and complex forms - recommended is a housing - magnetic holder.
- Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small components of these devices are able to be problematic in diagnostics medical in case of swallowing.
- Due to complex production process, their price is higher than average,
Holding force characteristics
Maximum lifting capacity of the magnet – what affects it?
- with the application of a sheet made of special test steel, guaranteeing full magnetic saturation
- with a cross-section of at least 10 mm
- with an ideally smooth touching surface
- under conditions of no distance (metal-to-metal)
- under axial force direction (90-degree angle)
- at ambient temperature room level
What influences lifting capacity in practice
- Gap between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Material composition – not every steel attracts identically. Alloy additives worsen the attraction effect.
- Surface finish – ideal contact is obtained only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Temperature influence – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate decreases the load capacity.
Warnings
Allergy Warning
Studies show that nickel (standard magnet coating) is a common allergen. For allergy sufferers, avoid touching magnets with bare hands or choose versions in plastic housing.
Dust explosion hazard
Mechanical processing of neodymium magnets poses a fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Protect data
Data protection: Strong magnets can ruin payment cards and delicate electronics (heart implants, medical aids, timepieces).
Permanent damage
Avoid heat. NdFeB magnets are susceptible to temperature. If you need operation above 80°C, inquire about HT versions (H, SH, UH).
Danger to pacemakers
Warning for patients: Strong magnetic fields affect medical devices. Maintain at least 30 cm distance or ask another person to work with the magnets.
Do not give to children
Always keep magnets out of reach of children. Choking hazard is significant, and the effects of magnets clamping inside the body are fatal.
Protective goggles
Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Serious injuries
Risk of injury: The attraction force is so great that it can cause hematomas, pinching, and even bone fractures. Protective gloves are recommended.
Respect the power
Before starting, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
Threat to navigation
GPS units and smartphones are highly susceptible to magnetism. Close proximity with a strong magnet can decalibrate the sensors in your phone.
