Advantages and disadvantages of neodymium magnets.
Advantages
- They do not lose magnetism, even over approximately ten years – the drop in power is only ~1% (based on measurements),
- They possess excellent resistance to magnetism drop as a result of external fields,
- In other words, due to the metallic finish of gold, the element becomes visually attractive,
- The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
- 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...
- Considering the possibility of free shaping and customization to individualized needs, magnetic components can be produced in a broad palette of shapes and sizes, which expands the range of possible applications,
- Versatile presence in advanced technology sectors – they serve a role in hard drives, electric drive systems, diagnostic systems, as well as other advanced devices.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Weaknesses
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- We suggest casing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complicated forms.
- Possible danger related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the context of child health protection. Furthermore, 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
Pull force analysis
Magnetic strength at its maximum – what affects it?
- on a block made of mild steel, optimally conducting the magnetic field
- whose transverse dimension equals approx. 10 mm
- with an ideally smooth touching surface
- without the slightest clearance between the magnet and steel
- during detachment in a direction perpendicular to the mounting surface
- at temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Clearance – existence of foreign body (paint, dirt, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Plate thickness – too thin plate does not close the flux, causing part of the flux to be escaped to the other side.
- Chemical composition of the base – low-carbon steel attracts best. Alloy steels reduce magnetic permeability and holding force.
- Base smoothness – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Thermal environment – temperature increase causes a temporary drop of induction. Check the thermal limit for a given model.
Lifting capacity was measured using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the load capacity is reduced by as much as fivefold. In addition, even a slight gap between the magnet and the plate reduces the holding force.
Warnings
Fragile material
Protect your eyes. Magnets can explode upon violent connection, launching shards into the air. Wear goggles.
Medical implants
People with a heart stimulator must keep an safe separation from magnets. The magnetic field can stop the functioning of the implant.
Phone sensors
GPS units and mobile phones are extremely sensitive to magnetism. Direct contact with a strong magnet can ruin the sensors in your phone.
Maximum temperature
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.
Allergic reactions
A percentage of the population experience a contact allergy to Ni, which is the typical protective layer for NdFeB magnets. Extended handling can result in an allergic reaction. We strongly advise wear safety gloves.
Respect the power
Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
No play value
NdFeB magnets are not suitable for play. Eating several magnets may result in them attracting across intestines, which poses a direct threat to life and requires immediate surgery.
Finger safety
Large magnets can smash fingers in a fraction of a second. Do not place your hand betwixt two attracting surfaces.
Electronic hazard
Avoid bringing magnets near a wallet, computer, or TV. The magnetic field can permanently damage these devices and wipe information from cards.
Combustion hazard
Drilling and cutting of NdFeB material poses a fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
