Pros and cons of rare earth magnets.
Benefits
- They have constant strength, and over nearly ten years their performance decreases symbolically – ~1% (in testing),
- Magnets perfectly defend themselves against loss of magnetization caused by ambient magnetic noise,
- Thanks to the glossy finish, the coating of nickel, gold, or silver-plated gives an clean appearance,
- Magnetic induction on the working layer of the magnet is maximum,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Thanks to versatility in designing and the capacity to modify to complex applications,
- Significant place in high-tech industry – they find application in computer drives, electric motors, advanced medical instruments, and complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- Limited possibility of producing threads in the magnet and complex shapes - preferred is cover - magnetic holder.
- Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these devices can be problematic in diagnostics medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum magnetic pulling force – what it depends on?
- using a base made of high-permeability steel, acting as a magnetic yoke
- whose transverse dimension is min. 10 mm
- with a plane free of scratches
- under conditions of ideal adhesion (metal-to-metal)
- under vertical application of breakaway force (90-degree angle)
- at temperature room level
Lifting capacity in practice – influencing factors
- Clearance – the presence of any layer (rust, dirt, gap) interrupts the magnetic circuit, which reduces power rapidly (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 standardly several times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Steel grade – ideal substrate is high-permeability steel. Stainless steels may generate lower lifting capacity.
- Surface finish – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal factor – hot environment weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Holding force was tested 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 small distance between the magnet and the plate decreases the load capacity.
Safe handling of neodymium magnets
Warning for allergy sufferers
Nickel alert: The nickel-copper-nickel coating consists of nickel. If redness occurs, cease handling magnets and use protective gear.
Do not underestimate power
Before starting, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
Medical implants
Health Alert: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Shattering risk
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
Threat to navigation
Remember: rare earth magnets generate a field that interferes with sensitive sensors. Keep a safe distance from your phone, tablet, and navigation systems.
Serious injuries
Big blocks can crush fingers in a fraction of a second. Under no circumstances place your hand between two strong magnets.
Machining danger
Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
Keep away from children
Product intended for adults. Small elements can be swallowed, leading to severe trauma. Store away from children and animals.
Electronic devices
Very strong magnetic fields can destroy records on credit cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.
Demagnetization risk
Monitor thermal conditions. Exposing the magnet to high heat will ruin its magnetic structure and pulling force.
