Advantages as well as disadvantages of neodymium magnets.
Pros
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- Magnets very well resist against demagnetization caused by ambient magnetic noise,
- A magnet with a smooth silver surface has better aesthetics,
- They are known for high magnetic induction at the operating surface, which affects their effectiveness,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to the ability of free molding and customization to individualized projects, NdFeB magnets can be modeled in a variety of shapes and sizes, which expands the range of possible applications,
- Versatile presence in high-tech industry – they serve a role in hard drives, electromotive mechanisms, precision medical tools, as well as technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- 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
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Limited ability of making nuts in the magnet and complex forms - recommended is casing - magnet mounting.
- Health risk to health – tiny shards of magnets are risky, when accidentally swallowed, which becomes key in the context of child safety. It is also worth noting that tiny parts of these products are able to disrupt the diagnostic process 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
Highest magnetic holding force – what affects it?
- with the application of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- with a plane cleaned and smooth
- under conditions of no distance (metal-to-metal)
- for force acting at a right angle (in the magnet axis)
- at conditions approx. 20°C
What influences lifting capacity in practice
- Gap between magnet and steel – every millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Load vector – highest force is reached only during perpendicular pulling. The resistance to sliding of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Steel thickness – insufficiently thick steel does not accept the full field, causing part of the flux to be wasted to the other side.
- Plate material – low-carbon steel attracts best. Higher carbon content reduce magnetic properties and holding force.
- Base smoothness – the more even the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Temperature – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.
Lifting capacity was measured by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under parallel forces the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
Warnings
Magnetic interference
A strong magnetic field disrupts the operation of magnetometers in smartphones and navigation systems. Do not bring magnets close to a smartphone to prevent breaking the sensors.
Mechanical processing
Fire warning: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
Maximum temperature
Standard neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Electronic hazard
Data protection: Strong magnets can damage payment cards and sensitive devices (heart implants, medical aids, mechanical watches).
Sensitization to coating
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If an allergic reaction occurs, immediately stop handling magnets and wear gloves.
Adults only
Absolutely store magnets away from children. Risk of swallowing is high, and the effects of magnets connecting inside the body are fatal.
Life threat
Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Bodily injuries
Danger of trauma: The attraction force is so great that it can result in hematomas, crushing, and broken bones. Protective gloves are recommended.
Respect the power
Before use, read the rules. Sudden snapping can break the magnet or injure your hand. Be predictive.
Fragile material
NdFeB magnets are ceramic materials, which means they are prone to chipping. Clashing of two magnets leads to them cracking into shards.
