Pros as well as cons of rare earth magnets.
Benefits
- They have constant strength, and over more than ten years their attraction force decreases symbolically – ~1% (in testing),
- They are extremely resistant to demagnetization induced by presence of other magnetic fields,
- Thanks to the shimmering finish, the coating of Ni-Cu-Ni, gold-plated, or silver gives an modern appearance,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a distinguishing feature,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures reaching 230°C and above...
- Thanks to the ability of free shaping and customization to specialized projects, NdFeB magnets can be created in a wide range of shapes and sizes, which amplifies use scope,
- Fundamental importance in innovative solutions – they are utilized in computer drives, motor assemblies, advanced medical instruments, also multitasking production systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We suggest a housing - magnetic mount, due to difficulties in creating nuts inside the magnet and complicated forms.
- Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- Due to neodymium price, their price is relatively high,
Lifting parameters
Maximum magnetic pulling force – what it depends on?
- with the contact of a sheet made of special test steel, guaranteeing full magnetic saturation
- with a cross-section of at least 10 mm
- with a surface free of scratches
- with direct contact (no paint)
- for force acting at a right angle (in the magnet axis)
- in stable room temperature
Magnet lifting force in use – key factors
- Distance (betwixt the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Load vector – maximum parameter is obtained only during perpendicular pulling. The force required to slide of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Plate material – mild steel attracts best. Higher carbon content reduce magnetic properties and holding force.
- Surface structure – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Temperature – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate decreases the lifting capacity.
H&S for magnets
Serious injuries
Pinching hazard: The pulling power is so great that it can result in blood blisters, crushing, and even bone fractures. Use thick gloves.
Machining danger
Powder produced during grinding of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Magnet fragility
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
Allergy Warning
Some people experience a sensitization to Ni, which is the standard coating for neodymium magnets. Prolonged contact might lead to skin redness. It is best to wear safety gloves.
Life threat
For implant holders: Powerful magnets disrupt medical devices. Maintain minimum 30 cm distance or request help to handle the magnets.
No play value
Absolutely store magnets away from children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are life-threatening.
Do not underestimate power
Handle with care. Neodymium magnets act from a long distance and snap with huge force, often faster than you can move away.
Threat to electronics
Device Safety: Strong magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, timepieces).
GPS and phone interference
A strong magnetic field interferes with the functioning of magnetometers in phones and GPS navigation. Keep magnets close to a smartphone to prevent breaking the sensors.
Do not overheat magnets
Regular neodymium magnets (N-type) lose power when the temperature surpasses 80°C. The loss of strength is permanent.
