Strengths as well as weaknesses of rare earth magnets.
Advantages
- They do not lose power, even after nearly ten years – the reduction in lifting capacity is only ~1% (theoretically),
- Magnets very well protect themselves against loss of magnetization caused by ambient magnetic noise,
- Thanks to the metallic finish, the coating of nickel, gold, or silver-plated gives an visually attractive appearance,
- Magnetic induction on the working part of the magnet is very high,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to flexibility in constructing and the ability to modify to specific needs,
- Huge importance in advanced technology sectors – they serve a role in hard drives, motor assemblies, diagnostic systems, and modern systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also raises their durability
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability 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 secure oxidation as well as corrosion.
- Limited ability of making nuts in the magnet and complex forms - recommended is a housing - mounting mechanism.
- Possible danger related to microscopic parts of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. Additionally, small components of these magnets can complicate diagnosis medical after entering the body.
- With mass production the cost of neodymium magnets is a challenge,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what it depends on?
- with the use of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- with a thickness of at least 10 mm
- characterized by smoothness
- without the slightest air gap between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at room temperature
Determinants of practical lifting force of a magnet
- Clearance – the presence of foreign body (rust, dirt, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is available only during perpendicular pulling. The resistance to sliding of the magnet along the surface is usually many times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Plate material – mild steel attracts best. Alloy admixtures lower magnetic permeability and holding force.
- Surface condition – ground elements ensure maximum contact, which improves field saturation. Uneven metal weaken the grip.
- Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
H&S for magnets
Electronic devices
Powerful magnetic fields can erase data on payment cards, hard drives, and storage devices. Stay away of min. 10 cm.
Finger safety
Pinching hazard: The attraction force is so great that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Allergy Warning
Nickel alert: The nickel-copper-nickel coating consists of nickel. If skin irritation happens, immediately stop handling magnets and use protective gear.
Demagnetization risk
Standard neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. The loss of strength is permanent.
Magnets are brittle
Protect your eyes. Magnets can explode upon violent connection, launching shards into the air. Wear goggles.
Dust explosion hazard
Dust produced during machining of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
Handling guide
Use magnets with awareness. Their huge power can surprise even professionals. Plan your moves and do not underestimate their power.
Adults only
Absolutely store magnets away from children. Ingestion danger is significant, and the effects of magnets clamping inside the body are very dangerous.
Phone sensors
Note: rare earth magnets generate a field that interferes with sensitive sensors. Keep a safe distance from your mobile, device, and GPS.
ICD Warning
Individuals with a ICD should keep an large gap from magnets. The magnetic field can stop the functioning of the implant.
