Pros as well as cons of neodymium magnets.
Strengths
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (according to literature),
- They possess excellent resistance to magnetism drop as a result of external fields,
- A magnet with a shiny gold surface is more attractive,
- Magnetic induction on the working part of the magnet is maximum,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to flexibility in designing and the ability to customize to individual projects,
- Versatile presence in future technologies – they are used in mass storage devices, motor assemblies, diagnostic systems, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in small systems
Weaknesses
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets decrease their strength 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 stability even at temperatures up to 230°C
- 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 as well as corrosion.
- Due to limitations in creating nuts and complex forms in magnets, we propose using casing - magnetic mount.
- Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. Furthermore, tiny parts of these magnets are able to disrupt the diagnostic process 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
Detachment force of the magnet in optimal conditions – what contributes to it?
- with the contact of a sheet made of special test steel, guaranteeing full magnetic saturation
- with a cross-section no less than 10 mm
- with a surface cleaned and smooth
- under conditions of ideal adhesion (metal-to-metal)
- under vertical force vector (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Air gap (betwixt the magnet and the metal), as even a very small clearance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Steel type – mild steel gives the best results. Alloy admixtures decrease magnetic properties and lifting capacity.
- Surface structure – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was determined by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet and the plate decreases the load capacity.
H&S for magnets
Keep away from children
Strictly store magnets out of reach of children. Choking hazard is significant, and the effects of magnets clamping inside the body are fatal.
Shattering risk
Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.
GPS Danger
Note: rare earth magnets produce a field that interferes with precision electronics. Maintain a safe distance from your phone, tablet, and GPS.
Danger to pacemakers
Warning for patients: Strong magnetic fields affect medical devices. Maintain at least 30 cm distance or ask another person to handle the magnets.
Conscious usage
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
Permanent damage
Regular neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. Damage is permanent.
Sensitization to coating
Certain individuals suffer from a sensitization to Ni, which is the common plating for NdFeB magnets. Frequent touching can result in skin redness. We suggest use protective gloves.
Dust explosion hazard
Powder generated during machining of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Electronic devices
Device Safety: Strong magnets can damage payment cards and delicate electronics (pacemakers, hearing aids, mechanical watches).
Serious injuries
Watch your fingers. Two powerful magnets will snap together instantly with a force of massive weight, destroying anything in their path. Exercise extreme caution!
