Pros and cons of rare earth magnets.
Strengths
- They retain attractive force for around ten years – the drop is just ~1% (according to analyses),
- They have excellent resistance to magnetism drop when exposed to opposing magnetic fields,
- By applying a smooth layer of gold, the element acquires an aesthetic look,
- They feature high magnetic induction at the operating surface, which increases their power,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
- Due to the potential of precise shaping and adaptation to specialized needs, neodymium magnets can be produced in a wide range of forms and dimensions, which increases their versatility,
- Key role in innovative solutions – they are utilized in data components, electric motors, medical devices, as well as industrial machines.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Weaknesses
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its 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 durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in producing threads and complex shapes in magnets, we recommend using a housing - magnetic mount.
- Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these devices are able to disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Highest magnetic holding force – what contributes to it?
- on a plate made of mild steel, optimally conducting the magnetic field
- with a cross-section of at least 10 mm
- with an ground contact surface
- without the slightest clearance between the magnet and steel
- under vertical application of breakaway force (90-degree angle)
- at temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Clearance – the presence of any layer (paint, tape, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Load vector – maximum parameter 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).
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Material composition – different alloys attracts identically. High carbon content weaken the attraction effect.
- Smoothness – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Temperature influence – high temperature reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was determined with the use of a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate reduces the lifting capacity.
Safety rules for work with neodymium magnets
Danger to pacemakers
For implant holders: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or ask another person to work with the magnets.
Permanent damage
Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.
Cards and drives
Powerful magnetic fields can erase data on credit cards, HDDs, and other magnetic media. Stay away of min. 10 cm.
Allergic reactions
Allergy Notice: The nickel-copper-nickel coating contains nickel. If redness appears, cease working with magnets and wear gloves.
Physical harm
Danger of trauma: The attraction force is so great that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.
Danger to the youngest
Strictly store magnets out of reach of children. Choking hazard is high, and the effects of magnets connecting inside the body are life-threatening.
Dust explosion hazard
Fire warning: Rare earth powder is explosive. Avoid machining magnets without safety gear as this risks ignition.
Threat to navigation
Note: neodymium magnets generate a field that disrupts precision electronics. Keep a separation from your phone, tablet, and navigation systems.
Risk of cracking
Neodymium magnets are ceramic materials, meaning they are fragile like glass. Impact of two magnets leads to them cracking into small pieces.
Do not underestimate power
Handle with care. Rare earth magnets attract from a distance and snap with massive power, often quicker than you can move away.
