Advantages and disadvantages of neodymium magnets.
Strengths
- Their power remains stable, and after around 10 years it drops only by ~1% (theoretically),
- Neodymium magnets are characterized by remarkably resistant to demagnetization caused by magnetic disturbances,
- The use of an refined layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnetic induction on the working part of the magnet is very high,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Thanks to the potential of precise shaping and adaptation to unique solutions, NdFeB magnets can be modeled in a broad palette of shapes and sizes, which makes them more universal,
- Significant place in modern industrial fields – they are utilized in magnetic memories, brushless drives, medical equipment, also technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Limitations
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength 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
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- We suggest a housing - magnetic holder, due to difficulties in producing threads inside the magnet and complex forms.
- Health risk related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, tiny parts of these magnets are able to complicate diagnosis medical in case of swallowing.
- Due to neodymium price, their price is higher than average,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- using a base made of mild steel, acting as a circuit closing element
- with a cross-section of at least 10 mm
- with a plane cleaned and smooth
- with direct contact (without impurities)
- during pulling in a direction perpendicular to the mounting surface
- at conditions approx. 20°C
Practical lifting capacity: influencing factors
- Clearance – existence of foreign body (paint, tape, gap) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Steel type – mild steel attracts best. Higher carbon content reduce magnetic properties and holding force.
- Surface finish – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal factor – high temperature reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, in contrast under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate decreases the holding force.
Safety rules for work with neodymium magnets
Do not drill into magnets
Combustion risk: Rare earth powder is explosive. Do not process magnets in home conditions as this risks ignition.
Permanent damage
Avoid heat. Neodymium magnets are susceptible to heat. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Danger to the youngest
NdFeB magnets are not suitable for play. Swallowing multiple magnets can lead to them pinching intestinal walls, which constitutes a critical condition and necessitates urgent medical intervention.
GPS and phone interference
A strong magnetic field negatively affects the functioning of compasses in phones and navigation systems. Maintain magnets near a device to avoid breaking the sensors.
Magnets are brittle
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
Allergy Warning
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If skin irritation appears, immediately stop working with magnets and use protective gear.
Serious injuries
Danger of trauma: The attraction force is so great that it can cause hematomas, pinching, and broken bones. Protective gloves are recommended.
Data carriers
Do not bring magnets close to a wallet, laptop, or TV. The magnetic field can destroy these devices and wipe information from cards.
Danger to pacemakers
Medical warning: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Handling guide
Be careful. Neodymium magnets act from a distance and snap with huge force, often quicker than you can react.
