Advantages and disadvantages of neodymium magnets.
Strengths
- They do not lose strength, even after nearly 10 years – the drop in power is only ~1% (according to tests),
- They show high resistance to demagnetization induced by external field influence,
- Thanks to the metallic finish, the surface of nickel, gold-plated, or silver-plated gives an clean appearance,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of accurate machining and optimizing to atypical needs,
- Key role in innovative solutions – they serve a role in magnetic memories, brushless drives, diagnostic systems, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which enables their usage in small systems
Disadvantages
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets lose strength 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Limited ability of making nuts in the magnet and complicated forms - recommended is cover - magnetic holder.
- Health risk resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the context of child safety. Furthermore, small components of these devices can disrupt the diagnostic process medical after entering the body.
- With large orders the cost of neodymium magnets is a challenge,
Lifting parameters
Best holding force of the magnet in ideal parameters – what affects it?
- using a sheet made of low-carbon steel, functioning as a circuit closing element
- possessing a thickness of min. 10 mm to avoid saturation
- with a plane free of scratches
- with zero gap (no coatings)
- under vertical force vector (90-degree angle)
- in temp. approx. 20°C
Lifting capacity in real conditions – factors
- Distance – existence of foreign body (rust, tape, air) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Load vector – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is usually many times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Material type – ideal substrate is pure iron steel. Cast iron may attract less.
- Base smoothness – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
- Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet and the plate reduces the holding force.
H&S for magnets
Beware of splinters
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Keep away from computers
Avoid bringing magnets close to a purse, laptop, or screen. The magnetism can permanently damage these devices and wipe information from cards.
Dust explosion hazard
Dust generated during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Serious injuries
Large magnets can crush fingers instantly. Do not place your hand betwixt two strong magnets.
Nickel allergy
Some people suffer from a contact allergy to nickel, which is the standard coating for NdFeB magnets. Prolonged contact can result in dermatitis. We recommend use safety gloves.
GPS Danger
Navigation devices and mobile phones are extremely susceptible to magnetism. Direct contact with a strong magnet can decalibrate the internal compass in your phone.
Implant safety
Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
No play value
These products are not toys. Accidental ingestion of multiple magnets can lead to them attracting across intestines, which poses a severe health hazard and necessitates urgent medical intervention.
Demagnetization risk
Standard neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Respect the power
Use magnets consciously. Their immense force can shock even experienced users. Stay alert and do not underestimate their force.
