Advantages as well as disadvantages of neodymium magnets.
Strengths
- They do not lose magnetism, even after around 10 years – the decrease in strength is only ~1% (based on measurements),
- Neodymium magnets prove to be exceptionally resistant to demagnetization caused by external magnetic fields,
- In other words, due to the metallic layer of gold, the element is aesthetically pleasing,
- They are known for high magnetic induction at the operating surface, which affects their effectiveness,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Possibility of detailed creating and optimizing to atypical requirements,
- Fundamental importance in electronics industry – they find application in data components, electric motors, diagnostic systems, also other advanced devices.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Disadvantages
- At strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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 extremely resistant to heat
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of making nuts in the magnet and complicated forms - preferred is cover - mounting mechanism.
- Potential hazard related to microscopic parts of magnets are risky, if swallowed, which gains importance in the context of child safety. Furthermore, tiny parts of these devices can complicate diagnosis medical in case of swallowing.
- With large orders the cost of neodymium magnets is a challenge,
Holding force characteristics
Maximum magnetic pulling force – what it depends on?
- with the use of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- whose transverse dimension is min. 10 mm
- with an ground touching surface
- under conditions of ideal adhesion (surface-to-surface)
- during detachment in a direction perpendicular to the plane
- at conditions approx. 20°C
Practical lifting capacity: influencing factors
- Distance – existence of foreign body (paint, tape, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Material type – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
- Surface condition – smooth surfaces ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
- Thermal environment – temperature increase results in weakening of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under parallel forces the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
H&S for magnets
Shattering risk
Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Dust explosion hazard
Fire warning: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
Choking Hazard
These products are not intended for children. Eating several magnets may result in them attracting across intestines, which poses a direct threat to life and necessitates immediate surgery.
Precision electronics
Navigation devices and mobile phones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Allergic reactions
It is widely known that nickel (the usual finish) is a strong allergen. If you have an allergy, refrain from direct skin contact or opt for coated magnets.
Implant safety
Individuals with a heart stimulator have to maintain an large gap from magnets. The magnetic field can disrupt the operation of the life-saving device.
Caution required
Handle with care. Neodymium magnets attract from a distance and connect with massive power, often faster than you can react.
Cards and drives
Avoid bringing magnets near a purse, computer, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
Physical harm
Big blocks can smash fingers in a fraction of a second. Do not place your hand between two strong magnets.
Do not overheat magnets
Do not overheat. NdFeB magnets are sensitive to heat. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
