Advantages and disadvantages of neodymium magnets.
Advantages
- They retain attractive force for nearly 10 years – the drop is just ~1% (according to analyses),
- They retain their magnetic properties even under external field action,
- The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnets are characterized by very high magnetic induction on the outer side,
- 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...
- Possibility of accurate forming and adjusting to individual needs,
- Universal use in modern technologies – they are utilized in computer drives, electromotive mechanisms, diagnostic systems, also industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which enables their usage in miniature devices
Cons
- At strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited possibility of producing threads in the magnet and complicated forms - recommended is casing - magnetic holder.
- Health risk resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. Furthermore, tiny parts of these products can complicate diagnosis medical when they are in the body.
- Due to expensive raw materials, their price is relatively high,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what affects it?
- on a block made of structural steel, effectively closing the magnetic flux
- whose transverse dimension equals approx. 10 mm
- characterized by even structure
- under conditions of no distance (metal-to-metal)
- under perpendicular force direction (90-degree angle)
- at room temperature
What influences lifting capacity in practice
- Distance (betwixt the magnet and the metal), as even a very small distance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Angle of force application – highest force is available only during perpendicular pulling. The resistance to sliding of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Steel type – mild steel attracts best. Alloy steels decrease magnetic permeability and holding force.
- Smoothness – full contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Temperature – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate lowers the holding force.
Precautions when working with neodymium magnets
Danger to the youngest
NdFeB magnets are not toys. Swallowing several magnets may result in them attracting across intestines, which poses a critical condition and requires immediate surgery.
GPS and phone interference
Navigation devices and mobile phones are extremely sensitive to magnetism. Direct contact with a strong magnet can ruin the sensors in your phone.
Fragile material
NdFeB magnets are ceramic materials, meaning they are prone to chipping. Clashing of two magnets will cause them cracking into small pieces.
Allergic reactions
Medical facts indicate that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, prevent touching magnets with bare hands and choose versions in plastic housing.
Magnetic media
Avoid bringing magnets near a wallet, computer, or TV. The magnetic field can destroy these devices and erase data from cards.
Heat sensitivity
Do not overheat. NdFeB magnets are susceptible to temperature. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Physical harm
Large magnets can break fingers instantly. Do not place your hand between two strong magnets.
Medical implants
For implant holders: Powerful magnets affect medical devices. Keep minimum 30 cm distance or ask another person to handle the magnets.
Safe operation
Handle magnets consciously. Their huge power can surprise even professionals. Plan your moves and respect their force.
Combustion hazard
Dust produced during grinding of magnets is flammable. Avoid drilling into magnets unless you are an expert.
