Strengths and weaknesses of neodymium magnets.
Strengths
- They retain attractive force for nearly ten years – the drop is just ~1% (in theory),
- Magnets perfectly protect themselves against demagnetization caused by ambient magnetic noise,
- In other words, due to the smooth surface of silver, the element looks attractive,
- The surface of neodymium magnets generates a strong magnetic field – this is a key feature,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures approaching 230°C and above...
- Possibility of accurate creating as well as adapting to defined needs,
- Universal use in future technologies – they serve a role in hard drives, electromotive mechanisms, medical devices, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which makes them useful in miniature devices
Cons
- To avoid cracks under impact, we recommend using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets experience a drop in strength. 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
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Limited ability of making threads in the magnet and complex shapes - recommended is casing - magnet mounting.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these products are able to be problematic in diagnostics medical after entering the body.
- With mass production the cost of neodymium magnets is a challenge,
Pull force analysis
Detachment force of the magnet in optimal conditions – what contributes to it?
- on a base made of mild steel, perfectly concentrating the magnetic flux
- whose thickness reaches at least 10 mm
- with a surface cleaned and smooth
- without any clearance between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Air gap (between the magnet and the metal), because even a tiny clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Direction of force – highest force is available only during perpendicular pulling. The resistance to sliding of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
- Base massiveness – too thin sheet causes magnetic saturation, causing part of the power to be escaped into the air.
- Metal type – different alloys attracts identically. Alloy additives weaken the interaction with the magnet.
- Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature influence – hot environment weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet’s surface and the plate decreases the load capacity.
H&S for magnets
Immense force
Before starting, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Beware of splinters
Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Bodily injuries
Risk of injury: The pulling power is so immense that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.
Do not give to children
Always store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are fatal.
Allergic reactions
It is widely known that nickel (standard magnet coating) is a strong allergen. If you have an allergy, prevent direct skin contact or opt for coated magnets.
Danger to pacemakers
Warning for patients: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or ask another person to handle the magnets.
Dust explosion hazard
Drilling and cutting of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Protect data
Device Safety: Neodymium magnets can damage payment cards and sensitive devices (heart implants, medical aids, mechanical watches).
Maximum temperature
Monitor thermal conditions. Exposing the magnet to high heat will destroy its magnetic structure and pulling force.
Compass and GPS
Remember: rare earth magnets generate a field that disrupts sensitive sensors. Maintain a separation from your phone, tablet, and GPS.
