Pros and cons of rare earth magnets.
Strengths
- They do not lose power, even during approximately 10 years – the decrease in strength is only ~1% (according to tests),
- Magnets effectively protect themselves against demagnetization caused by ambient magnetic noise,
- The use of an elegant finish of noble metals (nickel, gold, silver) causes the element to look better,
- Neodymium magnets achieve maximum magnetic induction on a small area, which ensures high operational effectiveness,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Due to the possibility of accurate shaping and customization to individualized projects, NdFeB magnets can be manufactured in a wide range of geometric configurations, which expands the range of possible applications,
- Universal use in modern technologies – they are utilized in hard drives, electric drive systems, diagnostic systems, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in compact constructions
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only secures them against impacts but also increases their durability
- Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited possibility of creating threads in the magnet and complicated forms - recommended is cover - magnet mounting.
- Health risk resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the context of child safety. Furthermore, small components of these magnets can disrupt the diagnostic process medical when they are in the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Lifting parameters
Highest magnetic holding force – what contributes to it?
- on a base made of mild steel, effectively closing the magnetic flux
- with a thickness no less than 10 mm
- characterized by smoothness
- without any air gap between the magnet and steel
- under axial force direction (90-degree angle)
- in temp. approx. 20°C
Practical aspects of lifting capacity – factors
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to pulling vertically. When slipping, the magnet holds much less (often approx. 20-30% of nominal force).
- Plate thickness – too thin sheet does not accept the full field, causing part of the flux to be wasted into the air.
- Material type – the best choice is high-permeability steel. Cast iron may attract less.
- Surface condition – smooth surfaces guarantee perfect abutment, which improves force. Rough surfaces weaken the grip.
- Thermal factor – high temperature reduces magnetic field. Too high temperature can permanently damage the magnet.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, however under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
Safety rules for work with NdFeB magnets
Flammability
Fire warning: Neodymium dust is highly flammable. Do not process magnets in home conditions as this risks ignition.
No play value
Always keep magnets away from children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are fatal.
Crushing risk
Large magnets can break fingers in a fraction of a second. Never put your hand betwixt two strong magnets.
ICD Warning
Warning for patients: Strong magnetic fields disrupt electronics. Maintain minimum 30 cm distance or request help to work with the magnets.
Data carriers
Equipment safety: Neodymium magnets can ruin payment cards and delicate electronics (heart implants, medical aids, mechanical watches).
Beware of splinters
Beware of splinters. Magnets can explode upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.
Warning for allergy sufferers
A percentage of the population experience a hypersensitivity to Ni, which is the common plating for neodymium magnets. Extended handling might lead to a rash. We suggest use protective gloves.
Handling guide
Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Keep away from electronics
An intense magnetic field negatively affects the functioning of compasses in phones and navigation systems. Maintain magnets close to a smartphone to avoid breaking the sensors.
Heat sensitivity
Keep cool. NdFeB magnets are sensitive to heat. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).
