Strengths and weaknesses of rare earth magnets.
Pros
- Their power is maintained, and after around 10 years it decreases only by ~1% (according to research),
- Magnets effectively protect themselves against demagnetization caused by ambient magnetic noise,
- A magnet with a metallic gold surface looks better,
- Neodymium magnets deliver maximum magnetic induction on a their surface, which allows for strong attraction,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to modularity in constructing and the ability to adapt to complex applications,
- Versatile presence in modern technologies – they find application in mass storage devices, brushless drives, precision medical tools, also modern systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- We recommend a housing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated forms.
- Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- Due to complex production process, their price exceeds standard values,
Holding force characteristics
Highest magnetic holding force – what it depends on?
- on a base made of structural steel, optimally conducting the magnetic flux
- whose thickness equals approx. 10 mm
- with an polished touching surface
- without the slightest insulating layer between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at ambient temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Clearance – the presence of foreign body (rust, tape, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
- Steel thickness – too thin steel causes magnetic saturation, causing part of the flux to be wasted to the other side.
- Chemical composition of the base – mild steel attracts best. Alloy admixtures lower magnetic permeability and holding force.
- Surface finish – full contact is possible only on smooth steel. Any scratches and bumps create air cushions, reducing force.
- Thermal environment – temperature increase results in weakening of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, however under shearing force the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet and the plate lowers the load capacity.
Precautions when working with NdFeB magnets
Magnetic interference
Navigation devices and mobile phones are highly susceptible to magnetism. Direct contact with a strong magnet can ruin the internal compass in your phone.
Machining danger
Machining of neodymium magnets carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Skin irritation risks
Studies show that nickel (standard magnet coating) is a common allergen. If you have an allergy, avoid direct skin contact and choose encased magnets.
Powerful field
Use magnets consciously. Their huge power can surprise even professionals. Stay alert and respect their power.
Life threat
Warning for patients: Strong magnetic fields disrupt medical devices. Maintain minimum 30 cm distance or ask another person to handle the magnets.
Demagnetization risk
Regular neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. This process is irreversible.
Eye protection
Despite metallic appearance, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Swallowing risk
Only for adults. Tiny parts can be swallowed, causing severe trauma. Keep out of reach of children and animals.
Serious injuries
Big blocks can crush fingers instantly. Under no circumstances place your hand betwixt two strong magnets.
Keep away from computers
Do not bring magnets near a wallet, computer, or screen. The magnetic field can permanently damage these devices and erase data from cards.
