Advantages as well as disadvantages of Nd2Fe14B magnets.
Strengths
- They have stable power, and over nearly 10 years their attraction force decreases symbolically – ~1% (in testing),
- Magnets perfectly protect themselves against demagnetization caused by external fields,
- Thanks to the shiny finish, the coating of Ni-Cu-Ni, gold-plated, or silver-plated gives an visually attractive appearance,
- They are known for high magnetic induction at the operating surface, which increases their power,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to flexibility in shaping and the capacity to modify to individual projects,
- Wide application in modern technologies – they are utilized in HDD drives, motor assemblies, diagnostic systems, as well as multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- At strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB 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
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- Limited ability of producing nuts in the magnet and complicated shapes - recommended is a housing - mounting mechanism.
- Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. Additionally, small components of these products can disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum holding power of the magnet – what it depends on?
- with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- possessing a thickness of min. 10 mm to avoid saturation
- characterized by even structure
- under conditions of ideal adhesion (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- at ambient temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Direction of force – maximum parameter is available only during perpendicular pulling. The shear force of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick plate causes magnetic saturation, causing part of the flux to be lost to the other side.
- Plate material – low-carbon steel attracts best. Higher carbon content reduce magnetic properties and holding force.
- Base smoothness – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Temperature – heating the magnet results in weakening of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Precautions when working with neodymium magnets
Crushing risk
Big blocks can crush fingers instantly. Under no circumstances put your hand betwixt two attracting surfaces.
Warning for allergy sufferers
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction appears, immediately stop handling magnets and wear gloves.
ICD Warning
Life threat: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Magnetic interference
Navigation devices and mobile phones are highly sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Electronic hazard
Very strong magnetic fields can erase data on payment cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.
Heat sensitivity
Standard neodymium magnets (N-type) lose power when the temperature surpasses 80°C. Damage is permanent.
Risk of cracking
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
Dust is flammable
Mechanical processing of neodymium magnets carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Handling rules
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Adults only
Only for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Store away from kids and pets.
