Advantages and disadvantages of neodymium magnets.
Strengths
- They retain full power for around 10 years – the loss is just ~1% (based on simulations),
- Neodymium magnets are remarkably resistant to magnetic field loss caused by external interference,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to look better,
- Magnetic induction on the working layer of the magnet turns out to be maximum,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of precise shaping and adjusting to specific applications,
- Key role in advanced technology sectors – they are commonly used in mass storage devices, brushless drives, advanced medical instruments, and multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Limitations
- To avoid cracks under impact, we suggest 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 advise our specialized [AH] magnets, which work effectively even at 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 stable to moisture, in case of application outdoors
- We suggest cover - magnetic mechanism, due to difficulties in creating threads inside the magnet and complicated forms.
- Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- Due to neodymium price, their price is relatively high,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what affects it?
- on a block made of mild steel, effectively closing the magnetic flux
- whose transverse dimension reaches at least 10 mm
- characterized by lack of roughness
- without the slightest insulating layer between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- in stable room temperature
Practical lifting capacity: influencing factors
- Air gap (between the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to varnish, rust or debris).
- Direction of force – maximum parameter is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin steel does not close the flux, causing part of the flux to be lost to the other side.
- Steel grade – the best choice is high-permeability steel. Stainless steels may generate lower lifting capacity.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases field saturation. Uneven metal weaken the grip.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under perpendicular forces, whereas under parallel forces the load capacity is reduced by as much as 5 times. In addition, even a slight gap between the magnet and the plate decreases the load capacity.
H&S for magnets
Risk of cracking
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Pacemakers
People with a heart stimulator should maintain an safe separation from magnets. The magnetic field can interfere with the operation of the implant.
Phone sensors
A strong magnetic field disrupts the functioning of compasses in smartphones and GPS navigation. Do not bring magnets near a device to prevent damaging the sensors.
Thermal limits
Keep cool. NdFeB magnets are susceptible to temperature. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).
This is not a toy
Adult use only. Tiny parts can be swallowed, causing serious injuries. Store out of reach of kids and pets.
Machining danger
Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Safe distance
Avoid bringing magnets near a wallet, laptop, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
Handling guide
Use magnets consciously. Their immense force can surprise even experienced users. Plan your moves and do not underestimate their power.
Allergy Warning
Medical facts indicate that the nickel plating (standard magnet coating) is a common allergen. If you have an allergy, refrain from direct skin contact and select coated magnets.
Hand protection
Risk of injury: The pulling power is so immense that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.
