Pros and cons of neodymium magnets.
Advantages
- Their power is maintained, and after around 10 years it decreases only by ~1% (according to research),
- Magnets effectively resist against demagnetization caused by foreign field sources,
- A magnet with a metallic gold surface looks better,
- Magnets are distinguished by maximum magnetic induction on the outer side,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of individual forming and modifying to precise conditions,
- Universal use in electronics industry – they serve a role in magnetic memories, electric drive systems, medical equipment, as well as multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in compact constructions
Disadvantages
- To avoid cracks under impact, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We recommend cover - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complex shapes.
- Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that tiny parts of these products are able to complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Maximum holding power of the magnet – what contributes to it?
- using a sheet made of high-permeability steel, acting as a magnetic yoke
- possessing a massiveness of at least 10 mm to ensure full flux closure
- characterized by lack of roughness
- without the slightest insulating layer between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at conditions approx. 20°C
Practical aspects of lifting capacity – factors
- Clearance – the presence of any layer (paint, tape, air) acts as an insulator, which reduces capacity rapidly (even by 50% at 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).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Material composition – different alloys reacts the same. Alloy additives worsen the attraction effect.
- Surface condition – ground elements ensure maximum contact, which increases force. Uneven metal reduce efficiency.
- Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet and the plate decreases the load capacity.
H&S for magnets
Pinching danger
Pinching hazard: The pulling power is so immense that it can result in hematomas, crushing, and broken bones. Use thick gloves.
Keep away from electronics
GPS units and smartphones are highly susceptible to magnetism. Close proximity with a strong magnet can decalibrate the sensors in your phone.
Do not drill into magnets
Dust produced during cutting of magnets is flammable. Avoid drilling into magnets unless you are an expert.
Threat to electronics
Avoid bringing magnets near a wallet, computer, or TV. The magnetism can destroy these devices and wipe information from cards.
Health Danger
Patients with a ICD have to keep an large gap from magnets. The magnetism can disrupt the operation of the life-saving device.
Conscious usage
Exercise caution. Rare earth magnets act from a distance and connect with massive power, often faster than you can react.
Heat warning
Standard neodymium magnets (grade N) lose power when the temperature surpasses 80°C. Damage is permanent.
Product not for children
Product intended for adults. Small elements can be swallowed, causing serious injuries. Store away from kids and pets.
Shattering risk
NdFeB magnets are sintered ceramics, which means they are very brittle. Collision of two magnets will cause them breaking into shards.
Nickel allergy
Nickel alert: The nickel-copper-nickel coating contains nickel. If redness happens, immediately stop handling magnets and wear gloves.
