Pros as well as cons of rare earth magnets.
Advantages
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (according to literature),
- They are extremely resistant to demagnetization induced by presence of other magnetic fields,
- In other words, due to the aesthetic finish of silver, the element is aesthetically pleasing,
- Neodymium magnets deliver maximum magnetic induction on a their surface, which increases force concentration,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to the ability of free forming and customization to individualized needs, neodymium magnets can be produced in a wide range of geometric configurations, which expands the range of possible applications,
- Key role in modern industrial fields – they serve a role in magnetic memories, electric motors, precision medical tools, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in compact constructions
Disadvantages
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a special holder, which not only protects them against impacts but also raises their durability
- Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We recommend a housing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complex forms.
- Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. It is also worth noting that small elements of these products can complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Maximum magnetic pulling force – what affects it?
- using a base made of mild steel, serving as a circuit closing element
- possessing a massiveness of minimum 10 mm to avoid saturation
- characterized by lack of roughness
- with direct contact (no impurities)
- for force acting at a right angle (pull-off, not shear)
- in stable room temperature
Lifting capacity in practice – influencing factors
- Clearance – existence of any layer (paint, tape, air) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Base massiveness – too thin steel does not close the flux, causing part of the flux to be escaped to the other side.
- Metal type – not every steel reacts the same. High carbon content worsen the interaction with the magnet.
- Smoothness – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal factor – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
H&S for magnets
Electronic devices
Equipment safety: Strong magnets can ruin payment cards and sensitive devices (pacemakers, hearing aids, timepieces).
Implant safety
For implant holders: Strong magnetic fields affect electronics. Maintain at least 30 cm distance or request help to handle the magnets.
Fragile material
Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Impact of two magnets leads to them cracking into shards.
Bone fractures
Protect your hands. Two large magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!
Nickel allergy
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction happens, cease handling magnets and use protective gear.
Product not for children
Strictly store magnets out of reach of children. Risk of swallowing is high, and the effects of magnets clamping inside the body are life-threatening.
GPS and phone interference
Remember: neodymium magnets generate a field that interferes with precision electronics. Maintain a safe distance from your mobile, device, and GPS.
Do not drill into magnets
Drilling and cutting of neodymium magnets carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Heat warning
Regular neodymium magnets (grade N) lose power when the temperature goes above 80°C. This process is irreversible.
Handling guide
Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
