Strengths and weaknesses of Nd2Fe14B magnets.
Strengths
- They have constant strength, and over more than ten years their attraction force decreases symbolically – ~1% (in testing),
- They are resistant to demagnetization induced by external magnetic fields,
- The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Neodymium magnets create maximum magnetic induction on a contact point, which allows for strong attraction,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures reaching 230°C and above...
- Possibility of detailed shaping as well as adapting to individual requirements,
- Key role in innovative solutions – they find application in data components, motor assemblies, diagnostic systems, also industrial machines.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Disadvantages
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- We suggest a housing - magnetic holder, due to difficulties in realizing threads inside the magnet and complex shapes.
- Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, small elements of these devices can be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Detachment force of the magnet in optimal conditions – what contributes to it?
- with the contact of a sheet made of special test steel, guaranteeing maximum field concentration
- whose transverse dimension equals approx. 10 mm
- with a plane free of scratches
- without the slightest insulating layer between the magnet and steel
- under axial force vector (90-degree angle)
- at ambient temperature room level
Practical aspects of lifting capacity – factors
- Space between magnet and steel – every millimeter of separation (caused e.g. by varnish or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Metal type – different alloys reacts the same. Alloy additives worsen the attraction effect.
- Plate texture – smooth surfaces ensure maximum contact, which improves force. Rough surfaces weaken the grip.
- Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was assessed with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.
Safety rules for work with NdFeB magnets
Magnetic media
Device Safety: Strong magnets can ruin data carriers and delicate electronics (pacemakers, hearing aids, mechanical watches).
Product not for children
Adult use only. Tiny parts can be swallowed, causing serious injuries. Store out of reach of children and animals.
Fire risk
Machining of NdFeB material poses a fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Impact on smartphones
Navigation devices and smartphones are highly susceptible to magnetic fields. Direct contact with a strong magnet can permanently damage the internal compass in your phone.
Medical implants
Health Alert: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Finger safety
Pinching hazard: The attraction force is so immense that it can result in hematomas, crushing, and broken bones. Use thick gloves.
Shattering risk
Neodymium magnets are ceramic materials, which means they are prone to chipping. Impact of two magnets leads to them shattering into shards.
Conscious usage
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
Metal Allergy
Medical facts indicate that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, avoid touching magnets with bare hands and choose versions in plastic housing.
Operating temperature
Watch the temperature. Heating the magnet to high heat will destroy its magnetic structure and pulling force.
