Pros as well as cons of neodymium magnets.
Benefits
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- Neodymium magnets remain exceptionally resistant to magnetic field loss caused by external interference,
- The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to look better,
- Magnetic induction on the surface of the magnet is strong,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Thanks to modularity in forming and the ability to adapt to client solutions,
- Universal use in advanced technology sectors – they are commonly used in hard drives, electromotive mechanisms, medical devices, as well as complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We recommend casing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complex forms.
- Potential hazard resulting from small fragments of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, small elements of these products can be problematic in diagnostics medical after entering the body.
- Due to complex production process, their price is higher than average,
Pull force analysis
Best holding force of the magnet in ideal parameters – what it depends on?
- with the contact of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- with a cross-section of at least 10 mm
- with a plane cleaned and smooth
- with total lack of distance (no coatings)
- during pulling in a direction vertical to the mounting surface
- at conditions approx. 20°C
Practical lifting capacity: influencing factors
- Air gap (betwixt the magnet and the plate), because even a microscopic clearance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Steel type – mild steel gives the best results. Alloy steels decrease magnetic permeability and lifting capacity.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces reduce efficiency.
- Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was assessed by applying a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate reduces the holding force.
Threat to electronics
Data protection: Strong magnets can ruin payment cards and sensitive devices (heart implants, medical aids, mechanical watches).
Thermal limits
Avoid heat. Neodymium magnets are sensitive to heat. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).
Protective goggles
Protect your eyes. Magnets can fracture upon violent connection, ejecting shards into the air. We recommend safety glasses.
Respect the power
Before use, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Adults only
Absolutely store magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are very dangerous.
Medical interference
Individuals with a heart stimulator have to keep an safe separation from magnets. The magnetism can interfere with the operation of the life-saving device.
Crushing risk
Pinching hazard: The attraction force is so immense that it can cause hematomas, crushing, and even bone fractures. Protective gloves are recommended.
GPS Danger
A powerful magnetic field interferes with the operation of magnetometers in phones and GPS navigation. Keep magnets close to a smartphone to prevent damaging the sensors.
Dust explosion hazard
Powder created during machining of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Metal Allergy
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If skin irritation appears, cease working with magnets and use protective gear.
