Pros and cons of neodymium magnets.
Benefits
- They have stable power, and over around ten years their performance decreases symbolically – ~1% (in testing),
- They do not lose their magnetic properties even under external field action,
- The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Possibility of precise modeling and adjusting to individual needs,
- Universal use in advanced technology sectors – they are commonly used in HDD drives, electric motors, precision medical tools, as well as modern systems.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Limitations
- To avoid cracks under impact, we suggest 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 force. Often, when the temperature exceeds 80°C, their strength 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 rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited possibility of making threads in the magnet and complicated forms - recommended is casing - magnetic holder.
- Possible danger to health – tiny shards of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small components of these products can be problematic in diagnostics medical in case of swallowing.
- Due to expensive raw materials, their price is relatively high,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what affects it?
- using a plate made of mild steel, serving as a ideal flux conductor
- possessing a thickness of at least 10 mm to ensure full flux closure
- characterized by smoothness
- without any insulating layer between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at room temperature
Lifting capacity in real conditions – factors
- Distance (betwixt the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Metal type – not every steel reacts the same. High carbon content weaken the attraction effect.
- Surface quality – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Thermal factor – high temperature weakens pulling force. Too high temperature can permanently damage the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a small distance between the magnet and the plate decreases the load capacity.
H&S for magnets
Keep away from children
Absolutely store magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are life-threatening.
Protective goggles
Beware of splinters. Magnets can fracture upon violent connection, ejecting shards into the air. Eye protection is mandatory.
Pacemakers
For implant holders: Powerful magnets affect electronics. Maintain minimum 30 cm distance or ask another person to handle the magnets.
Permanent damage
Do not overheat. Neodymium magnets are sensitive to temperature. If you require operation above 80°C, look for HT versions (H, SH, UH).
Data carriers
Intense magnetic fields can erase data on credit cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Keep away from electronics
An intense magnetic field disrupts the functioning of compasses in phones and GPS navigation. Keep magnets close to a device to avoid breaking the sensors.
Physical harm
Big blocks can smash fingers in a fraction of a second. Never place your hand between two strong magnets.
Safe operation
Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Nickel allergy
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation appears, immediately stop working with magnets and wear gloves.
Dust explosion hazard
Fire hazard: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.
