Strengths and weaknesses of rare earth magnets.
Strengths
- They do not lose strength, even during nearly ten years – the reduction in lifting capacity is only ~1% (according to tests),
- Neodymium magnets prove to be extremely resistant to magnetic field loss caused by external field sources,
- In other words, due to the metallic surface of silver, the element is aesthetically pleasing,
- Neodymium magnets create maximum magnetic induction on a their surface, which ensures high operational effectiveness,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to freedom in forming and the ability to modify to client solutions,
- Key role in modern industrial fields – they are utilized in HDD drives, brushless drives, diagnostic systems, and industrial machines.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited possibility of making nuts in the magnet and complicated shapes - recommended is casing - mounting mechanism.
- Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these devices can complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum magnetic pulling force – what contributes to it?
- using a base made of low-carbon steel, acting as a ideal flux conductor
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with an ideally smooth contact surface
- without the slightest insulating layer between the magnet and steel
- during pulling in a direction vertical to the plane
- in temp. approx. 20°C
Lifting capacity in real conditions – factors
- Clearance – the presence of foreign body (rust, tape, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Metal type – not every steel reacts the same. High carbon content weaken the interaction with the magnet.
- Surface finish – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Temperature influence – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate decreases the holding force.
H&S for magnets
This is not a toy
These products are not intended for children. Swallowing several magnets may result in them pinching intestinal walls, which constitutes a critical condition and requires urgent medical intervention.
Danger to pacemakers
Health Alert: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
GPS and phone interference
Navigation devices and mobile phones are highly sensitive to magnetism. Close proximity with a strong magnet can permanently damage the internal compass in your phone.
Handling rules
Handle magnets consciously. Their immense force can surprise even experienced users. Plan your moves and do not underestimate their power.
Cards and drives
Avoid bringing magnets close to a wallet, computer, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.
Risk of cracking
NdFeB magnets are ceramic materials, meaning they are very brittle. Impact of two magnets will cause them breaking into shards.
Dust is flammable
Dust created during grinding of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
Finger safety
Watch your fingers. Two powerful magnets will join instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Heat sensitivity
Do not overheat. NdFeB magnets are susceptible to heat. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Avoid contact if allergic
It is widely known that the nickel plating (the usual finish) is a strong allergen. If your skin reacts to metals, prevent touching magnets with bare hands and choose coated magnets.
