Strengths and weaknesses of neodymium magnets.
Pros
- Their strength is maintained, and after around ten years it drops only by ~1% (according to research),
- They are resistant to demagnetization induced by external disturbances,
- A magnet with a shiny gold surface has better aesthetics,
- Neodymium magnets generate maximum magnetic induction on a small area, which allows for strong attraction,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Thanks to freedom in shaping and the ability to adapt to individual projects,
- Significant place in innovative solutions – they are used in data components, motor assemblies, medical devices, also industrial machines.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Weaknesses
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
- 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.
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Limited possibility of making threads in the magnet and complicated shapes - recommended is casing - magnetic holder.
- Potential hazard resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. Additionally, small elements of these devices are able to be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum magnetic pulling force – what it depends on?
- with the contact of a sheet made of low-carbon steel, ensuring full magnetic saturation
- with a cross-section minimum 10 mm
- with an ideally smooth contact surface
- without any insulating layer between the magnet and steel
- during pulling in a direction vertical to the plane
- at temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Angle of force application – highest force is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is typically many times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Material type – the best choice is pure iron steel. Hardened steels may generate lower lifting capacity.
- Surface quality – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate reduces the holding force.
Precautions when working with NdFeB magnets
Immense force
Before starting, read the rules. Sudden snapping can break the magnet or injure your hand. Think ahead.
Bone fractures
Big blocks can break fingers instantly. Under no circumstances place your hand betwixt two strong magnets.
Magnetic media
Powerful magnetic fields can erase data on credit cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.
ICD Warning
Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Fragile material
Despite metallic appearance, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Nickel coating and allergies
Some people have a sensitization to Ni, which is the standard coating for neodymium magnets. Frequent touching may cause a rash. We recommend wear protective gloves.
Heat sensitivity
Watch the temperature. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and pulling force.
Mechanical processing
Dust created during cutting of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
This is not a toy
Neodymium magnets are not intended for children. Swallowing multiple magnets can lead to them attracting across intestines, which poses a direct threat to life and requires immediate surgery.
Impact on smartphones
Navigation devices and smartphones are extremely susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.
