Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- Their power remains stable, and after approximately ten years it decreases only by ~1% (theoretically),
- They are noted for resistance to demagnetization induced by external magnetic fields,
- In other words, due to the reflective layer of silver, the element is aesthetically pleasing,
- Magnetic induction on the working layer of the magnet remains maximum,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures reaching 230°C and above...
- Possibility of exact modeling and modifying to precise conditions,
- Universal use in advanced technology sectors – they are utilized in magnetic memories, electric drive systems, medical devices, also multitasking production systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We suggest casing - magnetic mount, due to difficulties in realizing nuts inside the magnet and complicated shapes.
- Health risk to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that tiny parts of these products can disrupt the diagnostic process medical when they are in the body.
- With mass production the cost of neodymium magnets is a challenge,
Lifting parameters
Highest magnetic holding force – what affects it?
- with the contact of a yoke made of special test steel, guaranteeing maximum field concentration
- with a thickness of at least 10 mm
- with an ground contact surface
- under conditions of gap-free contact (metal-to-metal)
- during pulling in a direction perpendicular to the plane
- at room temperature
Determinants of practical lifting force of a magnet
- Distance – the presence of any layer (paint, tape, gap) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is obtained 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 – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal reduce efficiency.
- Temperature influence – high temperature weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was determined using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
Precautions when working with NdFeB magnets
Serious injuries
Large magnets can smash fingers in a fraction of a second. Under no circumstances put your hand betwixt two attracting surfaces.
Avoid contact if allergic
Certain individuals have a hypersensitivity to nickel, which is the common plating for neodymium magnets. Extended handling might lead to a rash. We recommend wear safety gloves.
Keep away from computers
Do not bring magnets close to a wallet, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.
Magnet fragility
Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
ICD Warning
Health Alert: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.
Machining danger
Combustion risk: Rare earth powder is highly flammable. Do not process magnets without safety gear as this risks ignition.
Safe operation
Be careful. Rare earth magnets act from a long distance and connect with massive power, often quicker than you can react.
Phone sensors
A strong magnetic field negatively affects the operation of compasses in phones and navigation systems. Keep magnets near a smartphone to avoid breaking the sensors.
Choking Hazard
Neodymium magnets are not intended for children. Eating multiple magnets can lead to them connecting inside the digestive tract, which constitutes a severe health hazard and necessitates urgent medical intervention.
Thermal limits
Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
