Strengths as well as weaknesses of neodymium magnets.
Benefits
- They retain attractive force for almost ten years – the loss is just ~1% (based on simulations),
- They do not lose their magnetic properties even under close interference source,
- The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- They are known for high magnetic induction at the operating surface, which increases their power,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Possibility of detailed creating as well as adjusting to concrete conditions,
- Key role in advanced technology sectors – they are utilized in computer drives, motor assemblies, diagnostic systems, as well as other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Cons
- At very strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and 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 suggest using waterproof magnets e.g. in rubber, plastic
- We recommend a housing - magnetic mount, due to difficulties in producing nuts inside the magnet and complicated forms.
- Health risk to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Furthermore, tiny parts of these devices are able to complicate diagnosis medical when they are in the body.
- Due to neodymium price, their price is higher than average,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a base made of mild steel, optimally conducting the magnetic field
- whose thickness reaches at least 10 mm
- characterized by smoothness
- with direct contact (without coatings)
- during detachment in a direction vertical to the mounting surface
- in stable room temperature
Lifting capacity in real conditions – factors
- Clearance – the presence of any layer (rust, dirt, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds much less (often approx. 20-30% of nominal force).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Steel type – low-carbon steel gives the best results. Higher carbon content reduce magnetic properties and holding force.
- Surface finish – ideal contact is obtained only on smooth steel. Rough texture create air cushions, reducing force.
- Temperature influence – hot environment weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
Safety rules for work with NdFeB magnets
Do not overheat magnets
Avoid heat. Neodymium magnets are susceptible to temperature. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).
Avoid contact if allergic
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If skin irritation happens, immediately stop handling magnets and use protective gear.
Safe operation
Before starting, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
Keep away from electronics
Note: rare earth magnets generate a field that disrupts sensitive sensors. Maintain a safe distance from your mobile, device, and navigation systems.
Eye protection
Despite the nickel coating, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Pinching danger
Mind your fingers. Two powerful magnets will join instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Health Danger
For implant holders: Strong magnetic fields disrupt electronics. Maintain at least 30 cm distance or ask another person to work with the magnets.
Data carriers
Powerful magnetic fields can erase data on credit cards, HDDs, and other magnetic media. Keep a distance of min. 10 cm.
Do not give to children
Only for adults. Tiny parts can be swallowed, leading to serious injuries. Keep out of reach of children and animals.
Machining danger
Machining of neodymium magnets carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.
