Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- They have stable power, and over nearly ten years their attraction force decreases symbolically – ~1% (according to theory),
- Magnets perfectly protect themselves against loss of magnetization caused by foreign field sources,
- By using a lustrous coating of nickel, the element gains an nice look,
- They show high magnetic induction at the operating surface, which increases their power,
- 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 versatility in shaping and the ability to customize to client solutions,
- Significant place in electronics industry – they are utilized in mass storage devices, brushless drives, precision medical tools, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which allows their use in compact constructions
Weaknesses
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating threads and complex shapes in magnets, we recommend using cover - magnetic mechanism.
- Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small elements of these products are able to disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Magnetic strength at its maximum – what contributes to it?
- using a sheet made of high-permeability steel, functioning as a circuit closing element
- with a cross-section minimum 10 mm
- characterized by smoothness
- without the slightest clearance between the magnet and steel
- during pulling in a direction vertical to the mounting surface
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Plate material – mild steel gives the best results. Alloy steels lower magnetic permeability and holding force.
- Base smoothness – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Thermal environment – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, whereas under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.
Precautions when working with NdFeB magnets
Warning for allergy sufferers
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If redness happens, immediately stop working with magnets and use protective gear.
Adults only
These products are not intended for children. Accidental ingestion of a few magnets can lead to them attracting across intestines, which poses a direct threat to life and necessitates immediate surgery.
Phone sensors
Navigation devices and smartphones are extremely sensitive to magnetic fields. Direct contact with a strong magnet can decalibrate the sensors in your phone.
Serious injuries
Risk of injury: The attraction force is so great that it can cause hematomas, crushing, and even bone fractures. Protective gloves are recommended.
Handling guide
Before starting, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.
Danger to pacemakers
Warning for patients: Powerful magnets affect electronics. Keep at least 30 cm distance or ask another person to work with the magnets.
Combustion hazard
Fire warning: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.
Eye protection
Neodymium magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets leads to them shattering into shards.
Threat to electronics
Intense magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Do not overheat magnets
Watch the temperature. Exposing the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.
