Advantages as well as disadvantages of neodymium magnets.
Advantages
- They do not lose power, even during around 10 years – the reduction in power is only ~1% (based on measurements),
- They maintain their magnetic properties even under close interference source,
- The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to look better,
- They show high magnetic induction at the operating surface, which increases their power,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of accurate modeling and adjusting to defined needs,
- Universal use in high-tech industry – they find application in computer drives, electric motors, advanced medical instruments, and other advanced devices.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also increases 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 power. Therefore, we recommend our special magnets marked [AH], which maintain stability 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 nuts and complicated shapes in magnets, we recommend using a housing - magnetic mount.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small components of these products are able to be problematic in diagnostics medical when they are in the body.
- Due to expensive raw materials, their price is higher than average,
Pull force analysis
Detachment force of the magnet in optimal conditions – what contributes to it?
- using a sheet made of high-permeability steel, serving as a magnetic yoke
- whose thickness equals approx. 10 mm
- with an ground contact surface
- with total lack of distance (no impurities)
- during detachment in a direction vertical to the mounting surface
- at temperature room level
Lifting capacity in real conditions – factors
- Distance – existence of any layer (paint, dirt, air) acts as an insulator, which reduces power 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 usually several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Steel type – low-carbon steel attracts best. Alloy steels lower magnetic properties and holding force.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
- Thermal environment – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
H&S for magnets
Bodily injuries
Mind your fingers. Two powerful magnets will snap together immediately with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!
Product not for children
NdFeB magnets are not toys. Accidental ingestion of multiple magnets may result in them pinching intestinal walls, which poses a severe health hazard and necessitates urgent medical intervention.
Protective goggles
Despite metallic appearance, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.
Machining danger
Dust produced during grinding of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Electronic hazard
Very strong magnetic fields can destroy records on payment cards, hard drives, and storage devices. Maintain a gap of min. 10 cm.
Keep away from electronics
A strong magnetic field interferes with the operation of magnetometers in phones and GPS navigation. Keep magnets close to a device to avoid damaging the sensors.
Thermal limits
Regular neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Nickel coating and allergies
Some people suffer from a sensitization to nickel, which is the typical protective layer for NdFeB magnets. Extended handling can result in dermatitis. We recommend use protective gloves.
Medical implants
People with a pacemaker must keep an large gap from magnets. The magnetic field can stop the functioning of the implant.
Handling rules
Handle magnets consciously. Their powerful strength can surprise even experienced users. Plan your moves and do not underestimate their force.
