Strengths as well as weaknesses of rare earth magnets.
Pros
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (according to literature),
- Neodymium magnets prove to be exceptionally resistant to loss of magnetic properties caused by external interference,
- Thanks to the reflective finish, the plating of nickel, gold, or silver gives an professional appearance,
- Neodymium magnets create maximum magnetic induction on a contact point, which increases force concentration,
- 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 accurate molding and adaptation to custom needs, magnetic components can be created in a variety of forms and dimensions, which makes them more universal,
- Huge importance in innovative solutions – they find application in hard drives, brushless drives, medical equipment, also modern systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Limitations
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- We suggest cover - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complex shapes.
- Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which becomes key in the context of child health protection. Furthermore, tiny parts of these magnets are able to complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Best holding force of the magnet in ideal parameters – what contributes to it?
- using a sheet made of high-permeability steel, acting as a ideal flux conductor
- possessing a massiveness of minimum 10 mm to avoid saturation
- characterized by lack of roughness
- under conditions of gap-free contact (surface-to-surface)
- for force applied at a right angle (pull-off, not shear)
- at temperature room level
Magnet lifting force in use – key factors
- Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens 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 exhibits significantly lower power (typically approx. 20-30% of maximum force).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Steel grade – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
- Surface finish – ideal contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate reduces the lifting capacity.
Safe handling of neodymium magnets
Threat to navigation
An intense magnetic field disrupts the functioning of compasses in phones and GPS navigation. Do not bring magnets near a smartphone to prevent breaking the sensors.
Avoid contact if allergic
Certain individuals have a sensitization to nickel, which is the typical protective layer for neodymium magnets. Extended handling might lead to skin redness. It is best to wear safety gloves.
Thermal limits
Do not overheat. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, look for special high-temperature series (H, SH, UH).
Safe distance
Avoid bringing magnets close to a purse, laptop, or TV. The magnetic field can permanently damage these devices and wipe information from cards.
Adults only
Adult use only. Small elements pose a choking risk, causing severe trauma. Store away from children and animals.
Dust is flammable
Machining of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Hand protection
Mind your fingers. Two large magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!
Health Danger
Patients with a ICD have to keep an safe separation from magnets. The magnetic field can disrupt the operation of the implant.
Fragile material
Protect your eyes. Magnets can explode upon uncontrolled impact, launching shards into the air. Wear goggles.
Conscious usage
Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
