Pros as well as cons of Nd2Fe14B magnets.
Advantages
- They retain attractive force for almost ten years – the drop is just ~1% (based on simulations),
- Magnets perfectly protect themselves against demagnetization caused by external fields,
- In other words, due to the shiny surface of nickel, the element is aesthetically pleasing,
- The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures approaching 230°C and above...
- Possibility of individual forming and modifying to atypical requirements,
- Huge importance in high-tech industry – they are used in computer drives, drive modules, advanced medical instruments, also industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- At very strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in realizing nuts and complex forms in magnets, we propose using cover - magnetic mount.
- Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. Additionally, tiny parts of these devices can be problematic in diagnostics medical after entering the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Lifting parameters
Maximum magnetic pulling force – what contributes to it?
- with the application of a yoke made of special test steel, guaranteeing full magnetic saturation
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with an ground contact surface
- with zero gap (without paint)
- during detachment in a direction vertical to the mounting surface
- at standard ambient temperature
Impact of factors on magnetic holding capacity in practice
- Clearance – the presence of foreign body (rust, tape, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Material type – ideal substrate is pure iron steel. Hardened steels may attract less.
- Smoothness – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, however under shearing force the holding force is lower. Moreover, even a slight gap between the magnet and the plate decreases the load capacity.
Warnings
Fire warning
Drilling and cutting of NdFeB material carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Do not underestimate power
Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Choking Hazard
NdFeB magnets are not intended for children. Eating multiple magnets can lead to them connecting inside the digestive tract, which poses a critical condition and necessitates immediate surgery.
Warning for allergy sufferers
Medical facts indicate that the nickel plating (the usual finish) is a strong allergen. If your skin reacts to metals, avoid touching magnets with bare hands or opt for coated magnets.
Medical interference
People with a pacemaker must maintain an large gap from magnets. The magnetism can stop the operation of the implant.
Electronic hazard
Device Safety: Neodymium magnets can damage payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).
Keep away from electronics
Note: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a separation from your mobile, device, and navigation systems.
Fragile material
Neodymium magnets are ceramic materials, which means they are fragile like glass. Impact of two magnets will cause them cracking into shards.
Heat sensitivity
Standard neodymium magnets (grade N) lose power when the temperature exceeds 80°C. This process is irreversible.
Serious injuries
Protect your hands. Two powerful magnets will snap together immediately with a force of massive weight, destroying anything in their path. Exercise extreme caution!
