Pros and cons of rare earth magnets.
Advantages
- They retain attractive force for around ten years – the drop is just ~1% (according to analyses),
- They have excellent resistance to weakening of magnetic properties when exposed to opposing magnetic fields,
- By covering with a shiny layer of silver, the element presents an modern look,
- They show high magnetic induction at the operating surface, which improves attraction properties,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Possibility of accurate shaping as well as adjusting to complex needs,
- Huge importance in modern industrial fields – they find application in magnetic memories, motor assemblies, precision medical tools, also technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Cons
- At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
- Due to limitations in realizing nuts and complex forms in magnets, we propose using a housing - magnetic mount.
- Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. It is also worth noting that small elements of these magnets can complicate diagnosis medical when they are in the body.
- Due to complex production process, their price is relatively high,
Lifting parameters
Maximum magnetic pulling force – what affects it?
- with the application of a sheet made of low-carbon steel, ensuring maximum field concentration
- with a thickness no less than 10 mm
- characterized by lack of roughness
- with direct contact (no impurities)
- for force acting at a right angle (pull-off, not shear)
- in neutral thermal conditions
Practical aspects of lifting capacity – factors
- Distance – the presence of any layer (rust, tape, air) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Angle of force application – highest force is available only during pulling at a 90° angle. The force required to slide of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick plate does not close the flux, causing part of the flux to be escaped to the other side.
- Steel grade – ideal substrate is pure iron steel. Cast iron may attract less.
- Smoothness – full contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Temperature influence – hot environment reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was assessed using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
H&S for magnets
Phone sensors
Note: neodymium magnets produce a field that interferes with precision electronics. Keep a safe distance from your mobile, device, and GPS.
Mechanical processing
Dust produced during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Respect the power
Exercise caution. Neodymium magnets act from a long distance and connect with huge force, often quicker than you can move away.
Life threat
Patients with a pacemaker should maintain an safe separation from magnets. The magnetic field can stop the functioning of the life-saving device.
Skin irritation risks
Some people have a contact allergy to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching can result in skin redness. We recommend wear protective gloves.
Physical harm
Mind your fingers. Two large magnets will join immediately with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!
Maximum temperature
Control the heat. Heating the magnet to high heat will destroy its properties and strength.
Magnetic media
Device Safety: Strong magnets can ruin data carriers and delicate electronics (pacemakers, medical aids, mechanical watches).
Eye protection
NdFeB magnets are ceramic materials, which means they are very brittle. Collision of two magnets leads to them shattering into shards.
Adults only
Product intended for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Keep away from children and animals.
