Advantages and disadvantages of neodymium magnets.
Pros
- They have unchanged lifting capacity, and over around 10 years their performance decreases symbolically – ~1% (in testing),
- They maintain their magnetic properties even under close interference source,
- Thanks to the elegant finish, the plating of nickel, gold-plated, or silver gives an professional appearance,
- They are known for high magnetic induction at the operating surface, making them more effective,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures approaching 230°C and above...
- Considering the potential of accurate molding and adaptation to individualized projects, neodymium magnets can be modeled in a broad palette of shapes and sizes, which increases their versatility,
- Huge importance in electronics industry – they serve a role in data components, brushless drives, advanced medical instruments, also multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Weaknesses
- At strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can reduce their strength 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. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating nuts and complex forms in magnets, we propose using cover - magnetic mechanism.
- Health risk resulting from small fragments of magnets are risky, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small components of these magnets are able to be problematic in diagnostics medical when they are in the body.
- With budget limitations the cost of neodymium magnets is a challenge,
Lifting parameters
Maximum holding power of the magnet – what contributes to it?
- with the use of a yoke made of special test steel, ensuring maximum field concentration
- with a thickness no less than 10 mm
- with an ideally smooth contact surface
- under conditions of ideal adhesion (surface-to-surface)
- under axial force vector (90-degree angle)
- at conditions approx. 20°C
Practical aspects of lifting capacity – factors
- Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Load vector – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin steel does not accept the full field, causing part of the flux to be escaped to the other side.
- Material type – ideal substrate is high-permeability steel. Hardened steels may attract less.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
- Temperature influence – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate reduces the lifting capacity.
H&S for magnets
Dust explosion hazard
Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
ICD Warning
Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Heat warning
Keep cool. NdFeB magnets are sensitive to heat. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Finger safety
Protect your hands. Two large magnets will join instantly with a force of massive weight, crushing everything in their path. Be careful!
Risk of cracking
Despite metallic appearance, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Allergy Warning
Medical facts indicate that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, refrain from touching magnets with bare hands or opt for versions in plastic housing.
Safe operation
Before use, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
No play value
These products are not suitable for play. Accidental ingestion of multiple magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and requires urgent medical intervention.
GPS and phone interference
An intense magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Keep magnets near a smartphone to avoid breaking the sensors.
Keep away from computers
Powerful magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.
