Strengths and weaknesses of neodymium magnets.
Strengths
- They do not lose power, even during nearly 10 years – the drop in power is only ~1% (theoretically),
- They possess excellent resistance to magnetism drop due to external magnetic sources,
- A magnet with a smooth nickel surface has better aesthetics,
- They are known for high magnetic induction at the operating surface, which increases their power,
- 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 shaping and the capacity to customize to unusual requirements,
- Fundamental importance in future technologies – they are utilized in data components, motor assemblies, medical devices, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in compact constructions
Disadvantages
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding 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 stable to moisture, in case of application outdoors
- Limited ability of creating nuts in the magnet and complex shapes - preferred is cover - mounting mechanism.
- Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small elements of these magnets 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
Maximum holding power of the magnet – what contributes to it?
- on a base made of structural steel, effectively closing the magnetic flux
- possessing a massiveness of minimum 10 mm to avoid saturation
- with an ground contact surface
- under conditions of ideal adhesion (surface-to-surface)
- during detachment in a direction perpendicular to the plane
- at temperature room level
Magnet lifting force in use – key factors
- Gap (between the magnet and the metal), because even a tiny clearance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Direction of force – highest force is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the plate is typically several times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys attracts identically. High carbon content worsen the attraction effect.
- Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, reducing force.
- Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was determined with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, however under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
Life threat
Warning for patients: Powerful magnets affect medical devices. Maintain minimum 30 cm distance or ask another person to work with the magnets.
Precision electronics
An intense magnetic field interferes with the functioning of magnetometers in smartphones and navigation systems. Do not bring magnets close to a device to avoid damaging the sensors.
Cards and drives
Device Safety: Strong magnets can damage data carriers and delicate electronics (pacemakers, hearing aids, timepieces).
Risk of cracking
Protect your eyes. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
Dust explosion hazard
Powder created during machining of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Nickel allergy
A percentage of the population suffer from a contact allergy to nickel, which is the typical protective layer for neodymium magnets. Extended handling might lead to a rash. We suggest use safety gloves.
Adults only
Product intended for adults. Tiny parts can be swallowed, causing severe trauma. Keep out of reach of kids and pets.
Power loss in heat
Control the heat. Heating the magnet to high heat will destroy its magnetic structure and pulling force.
Crushing risk
Mind your fingers. Two powerful magnets will snap together immediately with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Safe operation
Be careful. Rare earth magnets act from a long distance and connect with huge force, often faster than you can move away.
