Pros and cons of Nd2Fe14B magnets.
Pros
- Their strength is durable, and after around 10 years it decreases only by ~1% (theoretically),
- Neodymium magnets are extremely resistant to demagnetization caused by external interference,
- In other words, due to the reflective layer of gold, the element gains visual value,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- In view of the possibility of accurate molding and adaptation to specialized requirements, magnetic components can be created in a variety of shapes and sizes, which makes them more universal,
- Key role in advanced technology sectors – they find application in mass storage devices, motor assemblies, precision medical tools, and technologically advanced constructions.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Cons
- To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases 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.
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- We recommend a housing - magnetic mount, due to difficulties in creating nuts inside the magnet and complicated shapes.
- Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. Additionally, small elements of these magnets are able to disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Highest magnetic holding force – what affects it?
- using a plate made of mild steel, acting as a circuit closing element
- whose transverse dimension reaches at least 10 mm
- with a plane free of scratches
- with zero gap (no coatings)
- under vertical force vector (90-degree angle)
- at temperature room level
Practical lifting capacity: influencing factors
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Steel thickness – too thin steel does not accept the full field, causing part of the flux to be escaped into the air.
- Steel type – mild steel attracts best. Alloy steels decrease magnetic permeability and lifting capacity.
- Base smoothness – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Temperature – temperature increase causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate reduces the holding force.
H&S for magnets
Fire warning
Powder created during cutting of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Eye protection
Despite the nickel coating, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
ICD Warning
Warning for patients: Powerful magnets disrupt electronics. Keep at least 30 cm distance or request help to work with the magnets.
Safe distance
Powerful magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Keep a distance of min. 10 cm.
Sensitization to coating
Certain individuals have a sensitization to nickel, which is the common plating for NdFeB magnets. Frequent touching can result in a rash. It is best to use protective gloves.
Do not underestimate power
Be careful. Rare earth magnets act from a distance and snap with huge force, often faster than you can react.
Bodily injuries
Danger of trauma: The attraction force is so immense that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.
GPS Danger
An intense magnetic field disrupts the functioning of magnetometers in smartphones and navigation systems. Keep magnets near a smartphone to avoid breaking the sensors.
Power loss in heat
Standard neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Product not for children
Product intended for adults. Small elements can be swallowed, leading to intestinal necrosis. Keep away from children and animals.
