Strengths as well as weaknesses of neodymium magnets.
Advantages
- Their magnetic field is maintained, and after approximately 10 years it drops only by ~1% (according to research),
- Neodymium magnets are remarkably resistant to loss of magnetic properties caused by external magnetic fields,
- Thanks to the shiny finish, the plating of Ni-Cu-Ni, gold-plated, or silver-plated gives an visually attractive appearance,
- They feature high magnetic induction at the operating surface, which increases their power,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Considering the option of flexible molding and customization to individualized requirements, magnetic components can be modeled in a variety of geometric configurations, which increases their versatility,
- Fundamental importance in high-tech industry – they are commonly used in mass storage devices, electromotive mechanisms, diagnostic systems, also multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a steel housing, which not only protects them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets experience a drop in power. 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
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We suggest casing - magnetic holder, due to difficulties in producing threads inside the magnet and complicated forms.
- Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, small components of these products can disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum magnetic pulling force – what it depends on?
- using a plate made of mild steel, functioning as a circuit closing element
- whose transverse dimension is min. 10 mm
- characterized by lack of roughness
- with total lack of distance (without impurities)
- during pulling in a direction vertical to the plane
- in temp. approx. 20°C
Practical lifting capacity: influencing factors
- Distance – existence of foreign body (rust, dirt, gap) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Steel type – low-carbon steel gives the best results. Alloy admixtures reduce magnetic properties and holding force.
- Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Rough surfaces reduce efficiency.
- Temperature influence – hot environment reduces magnetic field. Too high temperature can permanently damage the magnet.
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under perpendicular forces, whereas under parallel forces the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate reduces the holding force.
Warnings
Maximum temperature
Monitor thermal conditions. Heating the magnet to high heat will ruin its properties and strength.
Allergy Warning
Some people experience a sensitization to Ni, which is the common plating for NdFeB magnets. Prolonged contact may cause a rash. It is best to use safety 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.
Precision electronics
An intense magnetic field interferes with the operation of magnetometers in phones and GPS navigation. Maintain magnets near a device to prevent damaging the sensors.
Risk of cracking
Protect your eyes. Magnets can fracture upon violent connection, ejecting shards into the air. Eye protection is mandatory.
Physical harm
Protect your hands. Two large magnets will snap together instantly with a force of massive weight, crushing anything in their path. Be careful!
Swallowing risk
Product intended for adults. Tiny parts pose a choking risk, causing serious injuries. Keep out of reach of children and animals.
Life threat
Individuals with a heart stimulator have to keep an large gap from magnets. The magnetism can disrupt the functioning of the life-saving device.
Safe operation
Before use, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
Machining danger
Powder produced during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.
