Other products
Strengths as well as weaknesses of neodymium magnets.
Advantages
- They retain attractive force for almost 10 years – the loss is just ~1% (based on simulations),
- Magnets effectively defend themselves against demagnetization caused by ambient magnetic noise,
- Thanks to the shiny finish, the layer of Ni-Cu-Ni, gold-plated, or silver-plated gives an aesthetic appearance,
- Magnetic induction on the surface of the magnet remains exceptional,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures approaching 230°C and above...
- Thanks to freedom in designing and the capacity to modify to complex applications,
- Wide application in high-tech industry – they find application in mass storage devices, electric drive systems, precision medical tools, and industrial machines.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited possibility of creating threads in the magnet and complicated shapes - recommended is a housing - magnetic holder.
- Health risk related to microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. Additionally, small elements of these devices are able to disrupt the diagnostic process medical when they are in the body.
- Due to complex production process, their price is higher than average,
Lifting parameters
Maximum lifting force for a neodymium magnet – what affects it?
- on a plate made of mild steel, effectively closing the magnetic field
- with a thickness of at least 10 mm
- with a surface cleaned and smooth
- under conditions of gap-free contact (surface-to-surface)
- under vertical force direction (90-degree angle)
- in temp. approx. 20°C
Determinants of lifting force in real conditions
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Direction of force – maximum parameter is obtained only during perpendicular pulling. The shear force of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Metal type – different alloys attracts identically. High carbon content worsen the attraction effect.
- Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal environment – heating the magnet causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, however under parallel forces the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.
Safety rules for work with neodymium magnets
GPS and phone interference
A strong magnetic field interferes with the functioning of compasses in smartphones and navigation systems. Keep magnets close to a device to avoid breaking the sensors.
Machining danger
Mechanical processing of neodymium magnets poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Life threat
People with a heart stimulator should maintain an large gap from magnets. The magnetic field can interfere with the operation of the implant.
Nickel allergy
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If an allergic reaction occurs, immediately stop handling magnets and wear gloves.
Threat to electronics
Do not bring magnets close to a wallet, computer, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.
Do not give to children
Product intended for adults. Small elements pose a choking risk, causing serious injuries. Keep away from children and animals.
Powerful field
Before starting, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Maximum temperature
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its properties and pulling force.
Crushing risk
Danger of trauma: The attraction force is so immense that it can result in blood blisters, pinching, and broken bones. Protective gloves are recommended.
Protective goggles
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching shards into the air. Wear goggles.
