Pros as well as cons of Nd2Fe14B magnets.
Benefits
- They do not lose power, even during approximately 10 years – the decrease in lifting capacity is only ~1% (theoretically),
- They possess excellent resistance to magnetism drop as a result of external magnetic sources,
- Thanks to the metallic finish, the surface of Ni-Cu-Ni, gold-plated, or silver-plated gives an modern appearance,
- Magnetic induction on the working layer of the magnet turns out to be maximum,
- 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...
- In view of the possibility of free forming and adaptation to specialized needs, magnetic components can be produced in a wide range of forms and dimensions, which makes them more universal,
- Huge importance in modern technologies – they serve a role in HDD drives, electromotive mechanisms, diagnostic systems, also modern systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Cons
- At very strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of producing threads in the magnet and complicated forms - preferred is cover - magnetic holder.
- Potential hazard related to microscopic parts of magnets are risky, if swallowed, which gains importance in the context of child safety. Furthermore, small components of these magnets can complicate diagnosis medical in case of swallowing.
- With large orders the cost of neodymium magnets can be a barrier,
Holding force characteristics
Magnetic strength at its maximum – what it depends on?
- using a plate made of low-carbon steel, serving as a circuit closing element
- whose transverse dimension is min. 10 mm
- with a surface cleaned and smooth
- with direct contact (without coatings)
- under vertical force vector (90-degree angle)
- at room temperature
Lifting capacity in real conditions – factors
- Distance – existence of any layer (rust, tape, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Angle of force application – highest force is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys attracts identically. High carbon content weaken the interaction with the magnet.
- Base smoothness – the more even the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Temperature influence – high temperature reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was determined by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the load capacity is reduced by as much as 75%. Additionally, even a minimal clearance between the magnet and the plate lowers the holding force.
H&S for magnets
Bodily injuries
Mind your fingers. Two powerful magnets will join instantly with a force of massive weight, crushing anything in their path. Be careful!
Precision electronics
A strong magnetic field disrupts the functioning of compasses in phones and navigation systems. Maintain magnets close to a device to prevent damaging the sensors.
Nickel coating and allergies
Certain individuals suffer from a sensitization to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching might lead to skin redness. We recommend use safety gloves.
Do not overheat magnets
Control the heat. Heating the magnet to high heat will ruin its properties and strength.
Keep away from children
Strictly store magnets away from children. Risk of swallowing is high, and the effects of magnets clamping inside the body are fatal.
Magnetic media
Equipment safety: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, timepieces).
Conscious usage
Before use, read the rules. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
Mechanical processing
Dust created during cutting of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Danger to pacemakers
Health Alert: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Magnets are brittle
Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
