Strengths as well as weaknesses of neodymium magnets.
Strengths
- Their power is durable, and after around 10 years it drops only by ~1% (theoretically),
- Magnets perfectly defend themselves against loss of magnetization caused by foreign field sources,
- The use of an refined finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnetic induction on the working part of the magnet is strong,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Thanks to modularity in constructing and the ability to adapt to specific needs,
- Versatile presence in modern technologies – they are used in HDD drives, drive modules, diagnostic systems, and industrial machines.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Disadvantages
- To avoid cracks under impact, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We recommend casing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complex shapes.
- Health risk to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. Furthermore, small elements of these products 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
Holding force characteristics
Magnetic strength at its maximum – what contributes to it?
- with the contact of a yoke made of special test steel, guaranteeing full magnetic saturation
- with a cross-section no less than 10 mm
- characterized by even structure
- with zero gap (without paint)
- for force applied at a right angle (in the magnet axis)
- at room temperature
Practical lifting capacity: influencing factors
- Clearance – existence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of nominal force).
- Steel thickness – insufficiently thick sheet causes magnetic saturation, causing part of the power to be lost into the air.
- Material type – the best choice is pure iron steel. Stainless steels may have worse magnetic properties.
- Surface quality – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate lowers the holding force.
Safety rules for work with NdFeB magnets
Metal Allergy
Certain individuals experience a sensitization to Ni, which is the standard coating for neodymium magnets. Frequent touching might lead to dermatitis. It is best to use protective gloves.
Warning for heart patients
Warning for patients: Powerful magnets disrupt electronics. Keep at least 30 cm distance or request help to work with the magnets.
Danger to the youngest
Always store magnets away from children. Choking hazard is high, and the effects of magnets clamping inside the body are very dangerous.
Combustion hazard
Fire warning: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
Conscious usage
Before starting, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Serious injuries
Big blocks can break fingers instantly. Never place your hand between two strong magnets.
Material brittleness
NdFeB magnets are ceramic materials, meaning they are very brittle. Collision of two magnets leads to them shattering into shards.
Protect data
Data protection: Strong magnets can damage data carriers and delicate electronics (pacemakers, hearing aids, timepieces).
GPS and phone interference
Be aware: neodymium magnets produce a field that confuses sensitive sensors. Maintain a safe distance from your mobile, device, and GPS.
Demagnetization risk
Keep cool. Neodymium magnets are susceptible to temperature. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).
