Strengths as well as weaknesses of neodymium magnets.
Pros
- They retain magnetic properties for around ten years – the drop is just ~1% (based on simulations),
- They maintain their magnetic properties even under strong external field,
- Thanks to the elegant finish, the plating of Ni-Cu-Ni, gold, or silver-plated gives an modern appearance,
- Magnetic induction on the working part of the magnet remains maximum,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Considering the potential of accurate shaping and customization to specialized needs, NdFeB magnets can be produced in a broad palette of shapes and sizes, which increases their versatility,
- Versatile presence in innovative solutions – they are used in hard drives, motor assemblies, diagnostic systems, and technologically advanced constructions.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Weaknesses
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of creating nuts in the magnet and complicated forms - preferred is casing - magnetic holder.
- Possible danger to health – tiny shards of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small components of these products can complicate diagnosis medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum lifting capacity of the magnet – what affects it?
- using a sheet made of mild steel, functioning as a ideal flux conductor
- whose thickness is min. 10 mm
- with an ideally smooth contact surface
- with direct contact (no impurities)
- during pulling in a direction vertical to the mounting surface
- at temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Clearance – existence of foreign body (paint, dirt, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Plate thickness – too thin sheet does not close the flux, causing part of the flux to be wasted to the other side.
- Material type – ideal substrate is high-permeability steel. Stainless steels may generate lower lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
- Thermal environment – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, however under parallel forces the holding force is lower. Additionally, even a small distance between the magnet and the plate reduces the holding force.
Safety rules for work with neodymium magnets
Do not give to children
Strictly store magnets away from children. Ingestion danger is high, and the effects of magnets clamping inside the body are life-threatening.
Allergy Warning
Some people suffer from a contact allergy to Ni, which is the typical protective layer for NdFeB magnets. Frequent touching can result in an allergic reaction. We suggest use safety gloves.
Do not underestimate power
Handle magnets with awareness. Their powerful strength can shock even professionals. Be vigilant and do not underestimate their power.
Magnet fragility
Protect your eyes. Magnets can fracture upon violent connection, launching sharp fragments into the air. Wear goggles.
Maximum temperature
Regular neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Life threat
Life threat: Strong magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Fire risk
Machining of neodymium magnets carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Threat to navigation
A strong magnetic field interferes with the operation of compasses in smartphones and navigation systems. Keep magnets near a device to avoid breaking the sensors.
Crushing risk
Pinching hazard: The attraction force is so immense that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.
Magnetic media
Intense magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.
