Strengths and weaknesses of rare earth magnets.
Advantages
- They retain magnetic properties for nearly ten years – the loss is just ~1% (based on simulations),
- Neodymium magnets are remarkably resistant to loss of magnetic properties caused by magnetic disturbances,
- Thanks to the elegant finish, the coating of Ni-Cu-Ni, gold, or silver-plated gives an aesthetic appearance,
- Magnetic induction on the working layer of the magnet is impressive,
- 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...
- Possibility of accurate creating as well as optimizing to defined needs,
- Significant place in electronics industry – they are used in magnetic memories, motor assemblies, precision medical tools, and technologically advanced constructions.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets lose their power 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Limited possibility of creating nuts in the magnet and complicated forms - recommended is cover - mounting mechanism.
- Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, small components of these products are able to complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Detachment force of the magnet in optimal conditions – what it depends on?
- using a plate made of high-permeability steel, serving as a ideal flux conductor
- with a cross-section of at least 10 mm
- characterized by even structure
- with zero gap (without coatings)
- for force applied at a right angle (in the magnet axis)
- at temperature room level
Impact of factors on magnetic holding capacity in practice
- Air gap (between the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, corrosion or dirt).
- Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
- Plate thickness – too thin sheet does not accept the full field, causing part of the power to be wasted into the air.
- Metal type – not every steel attracts identically. High carbon content worsen the interaction with the magnet.
- Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Thermal factor – hot environment weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was measured with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
Sensitization to coating
Studies show that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, refrain from touching magnets with bare hands and opt for versions in plastic housing.
Data carriers
Avoid bringing magnets close to a purse, computer, or screen. The magnetic field can destroy these devices and wipe information from cards.
Fragile material
Beware of splinters. Magnets can explode upon violent connection, launching shards into the air. Eye protection is mandatory.
Threat to navigation
Navigation devices and smartphones are highly susceptible to magnetic fields. Close proximity with a strong magnet can ruin the internal compass in your phone.
Do not give to children
Only for adults. Small elements pose a choking risk, leading to serious injuries. Keep out of reach of children and animals.
Powerful field
Exercise caution. Neodymium magnets attract from a distance and snap with huge force, often quicker than you can react.
Combustion hazard
Drilling and cutting of neodymium magnets poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Danger to pacemakers
Warning for patients: Powerful magnets affect medical devices. Maintain minimum 30 cm distance or request help to handle the magnets.
Do not overheat magnets
Standard neodymium magnets (N-type) lose power when the temperature surpasses 80°C. Damage is permanent.
Serious injuries
Protect your hands. Two powerful magnets will snap together instantly with a force of massive weight, destroying anything in their path. Exercise extreme caution!
