Strengths as well as weaknesses of rare earth magnets.
Pros
- Their strength remains stable, and after approximately 10 years it drops only by ~1% (theoretically),
- They have excellent resistance to magnetism drop due to opposing magnetic fields,
- A magnet with a smooth silver surface has an effective appearance,
- The surface of neodymium magnets generates a unique magnetic field – this is one of their assets,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to flexibility in shaping and the ability to adapt to unusual requirements,
- Significant place in modern industrial fields – they are used in mass storage devices, drive modules, advanced medical instruments, also modern systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Disadvantages
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 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 those in rubber or plastics, which prevent oxidation as well as corrosion.
- Due to limitations in producing threads and complex shapes in magnets, we propose using a housing - magnetic mount.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. It is also worth noting that small components of these devices are able to complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Detachment force of the magnet in optimal conditions – what affects it?
- with the application of a yoke made of low-carbon steel, ensuring maximum field concentration
- possessing a thickness of min. 10 mm to avoid saturation
- characterized by lack of roughness
- without any air gap between the magnet and steel
- during pulling in a direction perpendicular to the mounting surface
- in stable room temperature
Determinants of lifting force in real conditions
- Distance – existence of foreign body (paint, dirt, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Steel thickness – too thin sheet does not close the flux, causing part of the power to be lost to the other side.
- Plate material – low-carbon steel gives the best results. Higher carbon content decrease magnetic permeability and lifting capacity.
- Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Temperature influence – hot environment weakens magnetic field. Too high temperature can permanently damage the magnet.
Lifting capacity was assessed with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet’s surface and the plate lowers the holding force.
Safe handling of neodymium magnets
Maximum temperature
Monitor thermal conditions. Heating the magnet to high heat will permanently weaken its properties and strength.
This is not a toy
Adult use only. Small elements can be swallowed, leading to serious injuries. Keep out of reach of children and animals.
Impact on smartphones
A powerful magnetic field negatively affects the operation of magnetometers in smartphones and navigation systems. Keep magnets close to a smartphone to prevent damaging the sensors.
Medical interference
For implant holders: Powerful magnets affect electronics. Keep at least 30 cm distance or ask another person to handle the magnets.
Magnet fragility
Despite metallic appearance, the material is brittle and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Combustion hazard
Machining of neodymium magnets poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Crushing risk
Big blocks can smash fingers in a fraction of a second. Never place your hand betwixt two attracting surfaces.
Caution required
Handle magnets consciously. Their huge power can shock even experienced users. Be vigilant and respect their power.
Electronic hazard
Do not bring magnets near a purse, computer, or screen. The magnetic field can destroy these devices and erase data from cards.
Nickel coating and allergies
Certain individuals experience a hypersensitivity to Ni, which is the typical protective layer for NdFeB magnets. Extended handling can result in skin redness. We suggest wear safety gloves.
