Pros as well as cons of rare earth magnets.
Benefits
- They have constant strength, and over around ten years their performance decreases symbolically – ~1% (in testing),
- They possess excellent resistance to magnetism drop as a result of opposing magnetic fields,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- They show high magnetic induction at the operating surface, making them more effective,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Due to the possibility of flexible shaping and adaptation to unique projects, neodymium magnets can be created in a wide range of forms and dimensions, which expands the range of possible applications,
- Wide application in modern industrial fields – they are used in mass storage devices, motor assemblies, medical equipment, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in compact constructions
Cons
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We suggest a housing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated forms.
- Health risk to health – tiny shards of magnets are risky, in case of ingestion, which gains importance in the context of child health protection. Furthermore, small elements of these magnets are able to complicate diagnosis medical after entering the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- on a base made of mild steel, effectively closing the magnetic flux
- possessing a thickness of min. 10 mm to ensure full flux closure
- with a plane free of scratches
- under conditions of ideal adhesion (surface-to-surface)
- during pulling in a direction perpendicular to the mounting surface
- at standard ambient temperature
Practical lifting capacity: influencing factors
- Gap (between the magnet and the metal), since even a tiny clearance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Plate material – mild steel attracts best. Alloy admixtures lower magnetic permeability and lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which improves force. Rough surfaces reduce efficiency.
- Temperature – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under perpendicular forces, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.
Warnings
Thermal limits
Control the heat. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.
Caution required
Handle with care. Rare earth magnets act from a long distance and snap with huge force, often quicker than you can react.
Risk of cracking
Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Nickel allergy
Certain individuals experience a hypersensitivity to Ni, which is the standard coating for NdFeB magnets. Frequent touching can result in a rash. We strongly advise use safety gloves.
ICD Warning
Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.
Pinching danger
Large magnets can break fingers instantly. Under no circumstances place your hand between two strong magnets.
Product not for children
Adult use only. Tiny parts pose a choking risk, leading to severe trauma. Store out of reach of children and animals.
Magnetic media
Do not bring magnets close to a wallet, computer, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.
Threat to navigation
A strong magnetic field disrupts the functioning of compasses in phones and navigation systems. Maintain magnets close to a smartphone to prevent breaking the sensors.
Dust explosion hazard
Fire hazard: Neodymium dust is explosive. Do not process magnets without safety gear as this risks ignition.
