Advantages and disadvantages of Nd2Fe14B magnets.
Pros
- They have constant strength, and over more than 10 years their attraction force decreases symbolically – ~1% (in testing),
- Neodymium magnets are distinguished by exceptionally resistant to magnetic field loss caused by external magnetic fields,
- Thanks to the elegant finish, the plating of nickel, gold, or silver gives an clean appearance,
- Magnets possess impressive magnetic induction on the working surface,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Thanks to the option of free forming and adaptation to custom needs, NdFeB magnets can be manufactured in a broad palette of forms and dimensions, which expands the range of possible applications,
- Significant place in modern technologies – they find application in computer drives, drive modules, advanced medical instruments, also multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Disadvantages
- 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.
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We suggest cover - magnetic mount, due to difficulties in creating threads inside the magnet and complex shapes.
- Possible danger to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these devices can 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
Maximum lifting force for a neodymium magnet – what contributes to it?
- with the use of a sheet made of special test steel, guaranteeing maximum field concentration
- with a cross-section no less than 10 mm
- with a plane free of scratches
- under conditions of ideal adhesion (surface-to-surface)
- under vertical force direction (90-degree angle)
- at temperature room level
Key elements affecting lifting force
- Clearance – existence of any layer (paint, tape, air) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Steel grade – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which improves force. Uneven metal reduce efficiency.
- Temperature influence – hot environment reduces magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a slight gap between the magnet and the plate decreases the lifting capacity.
Precautions when working with neodymium magnets
Cards and drives
Device Safety: Neodymium magnets can ruin data carriers and sensitive devices (pacemakers, medical aids, mechanical watches).
Handling rules
Use magnets consciously. Their huge power can shock even professionals. Stay alert and respect their force.
Hand protection
Big blocks can crush fingers in a fraction of a second. Never place your hand betwixt two strong magnets.
Swallowing risk
Strictly store magnets out of reach of children. Ingestion danger is high, and the consequences of magnets connecting inside the body are life-threatening.
Compass and GPS
Navigation devices and mobile phones are highly susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Medical implants
Health Alert: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Material brittleness
Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.
Fire warning
Dust produced during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Nickel allergy
Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. If you have an allergy, avoid direct skin contact or choose versions in plastic housing.
Operating temperature
Regular neodymium magnets (N-type) lose power when the temperature goes above 80°C. Damage is permanent.
