Pros and cons of neodymium magnets.
Benefits
- They do not lose strength, even during nearly ten years – the drop in lifting capacity is only ~1% (based on measurements),
- Magnets perfectly resist against demagnetization caused by foreign field sources,
- The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnetic induction on the working part of the magnet is strong,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to the potential of accurate forming and customization to individualized requirements, neodymium magnets can be manufactured in a variety of geometric configurations, which increases their versatility,
- Versatile presence in future technologies – they are used in computer drives, motor assemblies, precision medical tools, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which enables their usage in compact constructions
Weaknesses
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We suggest casing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complex shapes.
- Health risk to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these magnets can complicate diagnosis medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum magnetic pulling force – what affects it?
- on a base made of structural steel, perfectly concentrating the magnetic field
- whose transverse dimension is min. 10 mm
- with an ground contact surface
- under conditions of gap-free contact (surface-to-surface)
- under vertical application of breakaway force (90-degree angle)
- in neutral thermal conditions
Practical lifting capacity: influencing factors
- Clearance – existence of foreign body (rust, tape, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Metal type – different alloys attracts identically. Alloy additives worsen the attraction effect.
- Surface quality – the more even the plate, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
- Thermal environment – temperature increase causes a temporary drop of force. Check the thermal limit for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.
Safety rules for work with NdFeB magnets
Heat warning
Standard neodymium magnets (grade N) lose power when the temperature surpasses 80°C. The loss of strength is permanent.
Fragile material
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Safe operation
Handle magnets with awareness. Their immense force can shock even professionals. Stay alert and do not underestimate their power.
Warning for allergy sufferers
Nickel alert: The nickel-copper-nickel coating contains nickel. If an allergic reaction occurs, immediately stop working with magnets and use protective gear.
Bodily injuries
Danger of trauma: The pulling power is so great that it can cause hematomas, pinching, and even bone fractures. Use thick gloves.
Danger to the youngest
Strictly keep magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are life-threatening.
Dust explosion hazard
Combustion risk: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.
Phone sensors
GPS units and mobile phones are highly sensitive to magnetism. Close proximity with a strong magnet can permanently damage the sensors in your phone.
Pacemakers
People with a pacemaker have to maintain an absolute distance from magnets. The magnetism can stop the operation of the implant.
Data carriers
Avoid bringing magnets near a purse, laptop, or screen. The magnetism can permanently damage these devices and wipe information from cards.
