Pros and cons of Nd2Fe14B magnets.
Strengths
- They do not lose magnetism, even after around ten years – the decrease in power is only ~1% (based on measurements),
- Neodymium magnets are characterized by exceptionally resistant to demagnetization caused by external magnetic fields,
- A magnet with a shiny gold surface looks better,
- They are known for high magnetic induction at the operating surface, making them more effective,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Considering the option of accurate forming and customization to custom solutions, NdFeB magnets can be produced in a wide range of forms and dimensions, which amplifies use scope,
- Wide application in modern technologies – they serve a role in HDD drives, electric drive systems, medical devices, as well as industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- At very strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Limited ability of making threads in the magnet and complicated shapes - preferred is casing - magnetic holder.
- Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, small components of these devices can be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- using a base made of mild steel, acting as a ideal flux conductor
- with a thickness of at least 10 mm
- characterized by smoothness
- under conditions of ideal adhesion (metal-to-metal)
- during detachment in a direction vertical to the mounting surface
- at conditions approx. 20°C
Practical aspects of lifting capacity – factors
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Angle of force application – highest force is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel gives the best results. Alloy steels decrease magnetic permeability and holding force.
- Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Temperature influence – high temperature weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was measured using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the load capacity is reduced by as much as 75%. In addition, even a slight gap between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
Threat to electronics
Device Safety: Strong magnets can damage payment cards and sensitive devices (pacemakers, medical aids, timepieces).
Protective goggles
Watch out for shards. Magnets can fracture upon violent connection, launching sharp fragments into the air. Wear goggles.
Combustion hazard
Fire hazard: Rare earth powder is highly flammable. Do not process magnets in home conditions as this risks ignition.
Danger to the youngest
Strictly store magnets out of reach of children. Choking hazard is significant, and the consequences of magnets clamping inside the body are life-threatening.
Handling guide
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Crushing force
Risk of injury: The pulling power is so great that it can result in blood blisters, crushing, and even bone fractures. Protective gloves are recommended.
Thermal limits
Avoid heat. Neodymium magnets are sensitive to heat. If you need resistance above 80°C, look for special high-temperature series (H, SH, UH).
Nickel coating and allergies
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction occurs, immediately stop handling magnets and use protective gear.
Phone sensors
Note: rare earth magnets produce a field that interferes with sensitive sensors. Keep a separation from your phone, device, and GPS.
Implant safety
Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
