Strengths and weaknesses of neodymium magnets.
Strengths
- They retain magnetic properties for nearly 10 years – the loss is just ~1% (according to analyses),
- Magnets perfectly resist against demagnetization caused by external fields,
- The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
- 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...
- Possibility of individual shaping as well as adapting to defined conditions,
- Key role in high-tech industry – they find application in mass storage devices, electric motors, medical equipment, as well as multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Weaknesses
- To avoid cracks under impact, we recommend using special steel housings. Such a solution protects 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 strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Limited possibility of creating threads in the magnet and complex shapes - preferred is a housing - magnetic holder.
- Potential hazard resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small components of these magnets are able to be problematic in diagnostics 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
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- on a base made of structural steel, perfectly concentrating the magnetic flux
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- with a plane perfectly flat
- with direct contact (without coatings)
- for force applied at a right angle (in the magnet axis)
- at conditions approx. 20°C
Magnet lifting force in use – key factors
- Distance (between the magnet and the plate), since even a microscopic clearance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Direction of force – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Material composition – different alloys attracts identically. Alloy additives worsen the attraction effect.
- Surface finish – ideal contact is obtained only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Temperature – temperature increase results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity was assessed using a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate lowers the holding force.
Warnings
Crushing risk
Risk of injury: The pulling power is so immense that it can cause hematomas, pinching, and even bone fractures. Protective gloves are recommended.
Magnets are brittle
Despite the nickel coating, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Allergic reactions
It is widely known that the nickel plating (standard magnet coating) is a common allergen. If your skin reacts to metals, avoid direct skin contact or opt for versions in plastic housing.
Implant safety
Warning for patients: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or request help to handle the magnets.
Power loss in heat
Do not overheat. NdFeB magnets are sensitive to heat. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Safe distance
Device Safety: Strong magnets can damage data carriers and delicate electronics (pacemakers, medical aids, timepieces).
Caution required
Use magnets consciously. Their immense force can surprise even experienced users. Plan your moves and respect their power.
Precision electronics
GPS units and mobile phones are highly sensitive to magnetism. Close proximity with a strong magnet can decalibrate the internal compass in your phone.
Fire risk
Machining of NdFeB material carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Do not give to children
Product intended for adults. Tiny parts pose a choking risk, causing severe trauma. Store out of reach of children and animals.
