Magnetic properties of material
Physical properties of sintered neodymium magnets Nd2Fe14B at 20°C
Shopping tips
Advantages as well as disadvantages of NdFeB magnets.
Apart from their strong magnetic energy, neodymium magnets have these key benefits:
- They do not lose strength, even over approximately ten years – the decrease in lifting capacity is only ~1% (theoretically),
- They show high resistance to demagnetization induced by presence of other magnetic fields,
- A magnet with a smooth gold surface looks better,
- The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- In view of the ability of accurate forming and adaptation to unique projects, magnetic components can be modeled in a wide range of shapes and sizes, which amplifies use scope,
- Wide application in high-tech industry – they are commonly used in computer drives, electromotive mechanisms, medical devices, also technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Drawbacks and weaknesses of neodymium magnets and proposals for their use:
- Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a strong case, which not only secures them against impacts but also increases their durability
- Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We suggest a housing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complicated shapes.
- Potential hazard resulting from small fragments of magnets are risky, when accidentally swallowed, which is particularly important in the context of child safety. Furthermore, small components of these products are able to be problematic in diagnostics medical when they are in the body.
- Due to expensive raw materials, their price is relatively high,
Detachment force of the magnet in optimal conditions – what contributes to it?
The declared magnet strength refers to the maximum value, obtained under optimal environment, meaning:
- on a block made of structural steel, optimally conducting the magnetic field
- with a cross-section of at least 10 mm
- with a surface cleaned and smooth
- with total lack of distance (without coatings)
- for force applied at a right angle (pull-off, not shear)
- at ambient temperature room level
Magnet lifting force in use – key factors
In practice, the real power is determined by many variables, ranked from crucial:
- Clearance – existence of foreign body (rust, tape, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Base massiveness – too thin plate does not close the flux, causing part of the power to be escaped to the other side.
- Steel grade – the best choice is pure iron steel. Hardened steels may generate lower lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
- Thermal environment – temperature increase results in weakening 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 a perpendicular force was applied, in contrast under parallel forces the holding force is lower. Moreover, even a slight gap {between} the magnet’s surface and the plate decreases the load capacity.
Safety rules for work with neodymium magnets
Allergic reactions
Certain individuals suffer from a contact allergy to nickel, which is the standard coating for NdFeB magnets. Extended handling might lead to an allergic reaction. It is best to use protective gloves.
Finger safety
Pinching hazard: The pulling power is so great that it can result in hematomas, crushing, and broken bones. Use thick gloves.
Caution required
Handle magnets consciously. Their huge power can shock even professionals. Stay alert and respect their force.
Medical interference
Health Alert: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Material brittleness
Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Thermal limits
Watch the temperature. Exposing the magnet to high heat will destroy its properties and strength.
Combustion hazard
Machining of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Keep away from computers
Avoid bringing magnets close to a wallet, computer, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
Do not give to children
Neodymium magnets are not suitable for play. Accidental ingestion of multiple magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and necessitates immediate surgery.
Keep away from electronics
Be aware: neodymium magnets generate a field that confuses precision electronics. Maintain a separation from your mobile, tablet, and navigation systems.
