Other products
Strengths as well as weaknesses of rare earth magnets.
Advantages
- Their power is durable, and after around 10 years it drops only by ~1% (theoretically),
- Magnets very well resist against loss of magnetization caused by foreign field sources,
- By using a decorative coating of gold, the element presents an aesthetic look,
- They show high magnetic induction at the operating surface, which increases their power,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Thanks to versatility in designing and the capacity to customize to unusual requirements,
- Versatile presence in innovative solutions – they are utilized in data components, electric drive systems, advanced medical instruments, also other advanced devices.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets lose their force 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 durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Due to limitations in realizing threads and complicated forms in magnets, we recommend using cover - magnetic holder.
- Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these products are able to disrupt the diagnostic process medical after entering the body.
- With budget limitations the cost of neodymium magnets is a challenge,
Pull force analysis
Best holding force of the magnet in ideal parameters – what contributes to it?
- with the contact of a yoke made of special test steel, ensuring full magnetic saturation
- possessing a thickness of at least 10 mm to avoid saturation
- with a surface free of scratches
- with zero gap (no paint)
- under vertical force vector (90-degree angle)
- at temperature room level
Practical aspects of lifting capacity – factors
- Distance – the presence of any layer (rust, dirt, air) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Metal type – different alloys attracts identically. Alloy additives worsen the interaction with the magnet.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
- Temperature influence – high temperature reduces magnetic field. Too high temperature can permanently damage the magnet.
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the load capacity is reduced by as much as 75%. Moreover, even a slight gap between the magnet and the plate lowers the lifting capacity.
Safe handling of neodymium magnets
This is not a toy
Only for adults. Small elements pose a choking risk, leading to intestinal necrosis. Keep away from kids and pets.
Sensitization to coating
A percentage of the population experience a sensitization to Ni, which is the common plating for neodymium magnets. Frequent touching may cause dermatitis. We strongly advise wear protective gloves.
Risk of cracking
Beware of splinters. Magnets can explode upon violent connection, launching shards into the air. Wear goggles.
Phone sensors
An intense magnetic field negatively affects the operation of compasses in phones and navigation systems. Do not bring magnets close to a smartphone to avoid breaking the sensors.
Power loss in heat
Keep cool. Neodymium magnets are susceptible to temperature. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).
Safe distance
Data protection: Strong magnets can damage payment cards and sensitive devices (heart implants, medical aids, timepieces).
Caution required
Before use, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Life threat
Life threat: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Pinching danger
Protect your hands. Two powerful magnets will join immediately with a force of massive weight, destroying anything in their path. Be careful!
Combustion hazard
Drilling and cutting of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
