Pros and cons of rare earth magnets.
Benefits
- They do not lose strength, even after around ten years – the drop in lifting capacity is only ~1% (according to tests),
- Magnets perfectly protect themselves against demagnetization caused by external fields,
- Thanks to the shiny finish, the plating of Ni-Cu-Ni, gold, or silver gives an modern appearance,
- Neodymium magnets generate maximum magnetic induction on a their surface, which increases force concentration,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures reaching 230°C and above...
- Possibility of detailed creating as well as modifying to complex requirements,
- Versatile presence in electronics industry – they find application in HDD drives, electric motors, diagnostic systems, also complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a special holder, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets suffer a drop in strength. 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
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- Limited possibility of creating threads in the magnet and complicated forms - preferred is a housing - magnetic holder.
- Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these magnets are able to disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Best holding force of the magnet in ideal parameters – what contributes to it?
- with the application of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- whose thickness is min. 10 mm
- characterized by even structure
- without the slightest insulating layer between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- in temp. approx. 20°C
Determinants of lifting force in real conditions
- Air gap (betwixt the magnet and the plate), because even a tiny clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Direction of force – highest force is available only during perpendicular pulling. The shear force of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel gives the best results. Alloy steels reduce magnetic properties and lifting capacity.
- Surface structure – the more even the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Thermal factor – high temperature reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under shearing force the holding force is lower. In addition, even a small distance between the magnet and the plate lowers the holding force.
Safe handling of neodymium magnets
Magnetic media
Powerful magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.
Swallowing risk
These products are not intended for children. Accidental ingestion of multiple magnets may result in them attracting across intestines, which poses a direct threat to life and necessitates immediate surgery.
Do not drill into magnets
Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
Allergic reactions
A percentage of the population experience a sensitization to Ni, which is the typical protective layer for NdFeB magnets. Prolonged contact can result in skin redness. We recommend wear protective gloves.
Heat sensitivity
Avoid heat. Neodymium magnets are susceptible to heat. If you need operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Respect the power
Use magnets with awareness. Their huge power can surprise even experienced users. Be vigilant and respect their power.
Eye protection
Neodymium magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets will cause them breaking into shards.
Physical harm
Danger of trauma: The attraction force is so immense that it can result in blood blisters, crushing, and broken bones. Protective gloves are recommended.
Magnetic interference
A strong magnetic field negatively affects the functioning of compasses in phones and GPS navigation. Keep magnets near a device to avoid breaking the sensors.
Danger to pacemakers
People with a heart stimulator have to maintain an safe separation from magnets. The magnetism can stop the functioning of the life-saving device.
