Advantages as well as disadvantages of neodymium magnets.
Benefits
- They retain attractive force for nearly ten years – the drop is just ~1% (according to analyses),
- They are resistant to demagnetization induced by external magnetic fields,
- The use of an refined layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- The surface of neodymium magnets generates a powerful magnetic field – this is one of their assets,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Possibility of precise modeling as well as modifying to concrete requirements,
- Fundamental importance in innovative solutions – they find application in HDD drives, electric motors, precision medical tools, also multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Weaknesses
- At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing nuts and complicated shapes in magnets, we recommend using cover - magnetic mechanism.
- Possible danger resulting from small fragments of magnets are risky, if swallowed, which is particularly important in the context of child safety. It is also worth noting that tiny parts of these devices can disrupt the diagnostic process medical when they are in the body.
- With mass production the cost of neodymium magnets is a challenge,
Pull force analysis
Maximum lifting capacity of the magnet – what it depends on?
- using a base made of low-carbon steel, functioning as a magnetic yoke
- with a cross-section minimum 10 mm
- characterized by lack of roughness
- under conditions of gap-free contact (metal-to-metal)
- under vertical force vector (90-degree angle)
- at conditions approx. 20°C
Determinants of practical lifting force of a magnet
- Clearance – existence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
- Steel thickness – insufficiently thick plate does not close the flux, causing part of the power to be lost into the air.
- Plate material – low-carbon steel gives the best results. Higher carbon content lower magnetic properties and lifting capacity.
- Plate texture – ground elements ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
- Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate lowers the holding force.
Precautions when working with neodymium magnets
Skin irritation risks
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If an allergic reaction appears, immediately stop handling magnets and wear gloves.
Respect the power
Be careful. Neodymium magnets act from a long distance and snap with huge force, often faster than you can react.
Heat sensitivity
Do not overheat. Neodymium magnets are sensitive to temperature. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).
Compass and GPS
A strong magnetic field negatively affects the operation of magnetometers in phones and GPS navigation. Maintain magnets close to a device to avoid breaking the sensors.
Medical interference
Warning for patients: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or request help to work with the magnets.
Combustion hazard
Powder generated during grinding of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Data carriers
Intense magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.
Do not give to children
Strictly store magnets out of reach of children. Choking hazard is high, and the effects of magnets clamping inside the body are life-threatening.
Bone fractures
Pinching hazard: The pulling power is so great that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.
Fragile material
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
