Pros as well as cons of neodymium magnets.
Pros
- They retain attractive force for nearly ten years – the drop is just ~1% (based on simulations),
- Neodymium magnets are highly resistant to demagnetization caused by external field sources,
- The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures approaching 230°C and above...
- Considering the potential of free molding and adaptation to specialized needs, magnetic components can be created in a variety of geometric configurations, which increases their versatility,
- Fundamental importance in modern industrial fields – they are utilized in hard drives, electric drive systems, precision medical tools, as well as complex engineering applications.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Weaknesses
- To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets lose their force 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 stability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- We recommend a housing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated shapes.
- Possible danger related to microscopic parts of magnets are risky, if swallowed, which becomes key in the aspect of protecting the youngest. Additionally, tiny parts of these magnets are able to complicate diagnosis medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- with the application of a sheet made of special test steel, guaranteeing maximum field concentration
- whose thickness is min. 10 mm
- with a surface free of scratches
- with total lack of distance (without impurities)
- for force acting at a right angle (pull-off, not shear)
- in temp. approx. 20°C
Key elements affecting lifting force
- Clearance – existence of foreign body (paint, tape, gap) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Angle of force application – highest force is available only during perpendicular pulling. The shear force of the magnet along the surface is usually many times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Steel grade – the best choice is pure iron steel. Hardened steels may attract less.
- Plate texture – smooth surfaces ensure maximum contact, which improves force. Rough surfaces weaken the grip.
- Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under shearing force the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet and the plate decreases the load capacity.
H&S for magnets
Medical implants
Warning for patients: Strong magnetic fields disrupt medical devices. Maintain minimum 30 cm distance or ask another person to handle the magnets.
Caution required
Before starting, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Shattering risk
Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.
Heat warning
Standard neodymium magnets (grade N) lose power when the temperature exceeds 80°C. Damage is permanent.
Cards and drives
Do not bring magnets close to a wallet, laptop, or screen. The magnetic field can permanently damage these devices and wipe information from cards.
Flammability
Machining of neodymium magnets poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Warning for allergy sufferers
It is widely known that the nickel plating (standard magnet coating) is a common allergen. If you have an allergy, avoid direct skin contact and opt for versions in plastic housing.
Compass and GPS
Be aware: neodymium magnets generate a field that confuses sensitive sensors. Keep a separation from your phone, device, and GPS.
Crushing risk
Danger of trauma: The pulling power is so immense that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.
Swallowing risk
Neodymium magnets are not toys. Swallowing several magnets can lead to them pinching intestinal walls, which poses a direct threat to life and requires urgent medical intervention.
