Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- Their power is durable, and after around ten years it drops only by ~1% (according to research),
- They do not lose their magnetic properties even under external field action,
- By applying a decorative layer of silver, the element has an proper look,
- Magnetic induction on the working layer of the magnet turns out to be exceptional,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures reaching 230°C and above...
- In view of the option of flexible forming and adaptation to specialized requirements, NdFeB magnets can be modeled in a variety of shapes and sizes, which expands the range of possible applications,
- Huge importance in modern industrial fields – they are used in HDD drives, electric drive systems, diagnostic systems, as well as technologically advanced constructions.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a steel housing, which not only protects them against impacts but also raises their durability
- Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in realizing threads and complex forms in magnets, we propose using cover - magnetic holder.
- Possible danger related to microscopic parts of magnets are risky, if swallowed, which gains importance in the context of child safety. Furthermore, small components of these magnets can disrupt the diagnostic process medical after entering the body.
- Due to complex production process, their price is higher than average,
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what affects it?
- with the contact of a yoke made of special test steel, guaranteeing full magnetic saturation
- with a cross-section minimum 10 mm
- with a plane free of scratches
- without any clearance between the magnet and steel
- under perpendicular force direction (90-degree angle)
- at conditions approx. 20°C
What influences lifting capacity in practice
- Air gap (between the magnet and the metal), since even a microscopic distance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Direction of force – maximum parameter is reached only during perpendicular pulling. The resistance to sliding of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Material type – ideal substrate is high-permeability steel. Stainless steels may have worse magnetic properties.
- Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
- Temperature influence – hot environment reduces magnetic field. Too high temperature can permanently damage the magnet.
Lifting capacity was measured with the use of a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under attempts to slide the magnet the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate lowers the holding force.
H&S for magnets
Safe distance
Data protection: Strong magnets can damage payment cards and delicate electronics (heart implants, medical aids, mechanical watches).
Flammability
Machining of NdFeB material carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Operating temperature
Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
No play value
Adult use only. Small elements can be swallowed, causing severe trauma. Store away from kids and pets.
Handling rules
Handle magnets with awareness. Their powerful strength can shock even professionals. Plan your moves and do not underestimate their power.
Allergic reactions
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation happens, immediately stop handling magnets and wear gloves.
Magnets are brittle
Neodymium magnets are ceramic materials, meaning they are prone to chipping. Collision of two magnets will cause them shattering into small pieces.
Compass and GPS
An intense magnetic field interferes with the functioning of magnetometers in smartphones and navigation systems. Do not bring magnets near a smartphone to prevent breaking the sensors.
Warning for heart patients
Patients with a ICD have to maintain an large gap from magnets. The magnetic field can stop the functioning of the life-saving device.
Hand protection
Risk of injury: The pulling power is so great that it can result in hematomas, crushing, and even bone fractures. Protective gloves are recommended.
