Strengths and weaknesses of neodymium magnets.
Pros
- Their power remains stable, and after approximately 10 years it drops only by ~1% (theoretically),
- They do not lose their magnetic properties even under external field action,
- In other words, due to the glossy layer of gold, the element becomes visually attractive,
- Magnetic induction on the surface of the magnet is extremely intense,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Considering the option of precise forming and customization to specialized solutions, NdFeB magnets can be manufactured in a broad palette of geometric configurations, which makes them more universal,
- Significant place in innovative solutions – they are utilized in magnetic memories, drive modules, diagnostic systems, also complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which enables their usage in small systems
Limitations
- Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a strong case, which not only secures them against impacts but also increases their durability
- Neodymium magnets lose their power 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
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited possibility of creating nuts in the magnet and complicated shapes - preferred is cover - mounting mechanism.
- Health risk to health – tiny shards of magnets are risky, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these devices 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
Pull force analysis
Maximum lifting capacity of the magnet – what affects it?
- using a base made of mild steel, serving as a magnetic yoke
- with a cross-section minimum 10 mm
- with an ground touching surface
- under conditions of no distance (surface-to-surface)
- for force applied at a right angle (pull-off, not shear)
- in stable room temperature
What influences lifting capacity in practice
- Distance – existence of any layer (paint, tape, air) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Angle of force application – highest force is available only during pulling at a 90° angle. The force required to slide of the magnet along the surface is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Steel thickness – insufficiently thick plate causes magnetic saturation, causing part of the flux to be lost into the air.
- Material composition – not every steel reacts the same. High carbon content weaken the interaction with the magnet.
- Plate texture – ground elements ensure maximum contact, which improves force. Uneven metal reduce efficiency.
- Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was measured by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate lowers the load capacity.
Precautions when working with NdFeB magnets
Handling rules
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.
Permanent damage
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.
Bone fractures
Large magnets can break fingers instantly. Under no circumstances put your hand betwixt two strong magnets.
Life threat
For implant holders: Powerful magnets affect medical devices. Keep minimum 30 cm distance or request help to work with the magnets.
Flammability
Combustion risk: Rare earth powder is explosive. Avoid machining magnets in home conditions as this risks ignition.
Threat to electronics
Intense magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.
Choking Hazard
Adult use only. Small elements can be swallowed, causing intestinal necrosis. Keep out of reach of children and animals.
Beware of splinters
NdFeB magnets are ceramic materials, meaning they are very brittle. Clashing of two magnets will cause them breaking into shards.
Threat to navigation
Navigation devices and mobile phones are extremely sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.
Allergic reactions
It is widely known that nickel (the usual finish) is a common allergen. If you have an allergy, prevent touching magnets with bare hands and opt for coated magnets.
