Strengths and weaknesses of rare earth magnets.
Strengths
- Their magnetic field is maintained, and after approximately 10 years it drops only by ~1% (according to research),
- They show high resistance to demagnetization induced by external disturbances,
- The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Magnetic induction on the working part of the magnet is exceptional,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
- Considering the ability of flexible forming and customization to unique solutions, neodymium magnets can be created in a variety of shapes and sizes, which amplifies use scope,
- Fundamental importance in advanced technology sectors – they are utilized in magnetic memories, drive modules, diagnostic systems, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in compact constructions
Weaknesses
- At strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and 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 rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing threads and complicated shapes in magnets, we recommend using a housing - magnetic mount.
- 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 small components of these magnets can disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Maximum lifting capacity of the magnet – what it depends on?
- on a block made of structural steel, optimally conducting the magnetic field
- whose transverse dimension equals approx. 10 mm
- with an polished touching surface
- under conditions of ideal adhesion (surface-to-surface)
- for force acting at a right angle (pull-off, not shear)
- at standard ambient temperature
Practical aspects of lifting capacity – factors
- Clearance – existence of foreign body (rust, tape, gap) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Load vector – highest force is obtained only during perpendicular pulling. The shear force of the magnet along the plate is usually several 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).
- Chemical composition of the base – low-carbon steel gives the best results. Alloy admixtures decrease magnetic permeability and lifting capacity.
- Smoothness – ideal contact is possible only on polished steel. Rough texture reduce the real contact area, reducing force.
- Thermal environment – temperature increase causes a temporary drop of induction. Check the thermal limit for a given model.
Lifting capacity was determined with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet and the plate decreases the lifting capacity.
Warnings
Pacemakers
For implant holders: Strong magnetic fields affect electronics. Keep at least 30 cm distance or ask another person to work with the magnets.
Shattering risk
Watch out for shards. Magnets can explode upon violent connection, launching shards into the air. We recommend safety glasses.
Electronic hazard
Do not bring magnets close to a wallet, computer, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.
Threat to navigation
GPS units and smartphones are extremely sensitive to magnetic fields. Close proximity with a strong magnet can decalibrate the internal compass in your phone.
Heat sensitivity
Avoid heat. Neodymium magnets are susceptible to temperature. If you need resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Do not drill into magnets
Powder created during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Respect the power
Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Choking Hazard
Adult use only. Small elements can be swallowed, causing severe trauma. Keep away from kids and pets.
Allergy Warning
Certain individuals experience a contact allergy to nickel, which is the common plating for NdFeB magnets. Prolonged contact may cause skin redness. We suggest use safety gloves.
Serious injuries
Pinching hazard: The pulling power is so immense that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.
