Strengths as well as weaknesses of rare earth magnets.
Advantages
- They retain magnetic properties for around 10 years – the loss is just ~1% (in theory),
- Neodymium magnets are distinguished by remarkably resistant to loss of magnetic properties caused by external interference,
- A magnet with a shiny silver surface looks better,
- Neodymium magnets ensure maximum magnetic induction on a contact point, which increases force concentration,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures reaching 230°C and above...
- Possibility of individual modeling as well as optimizing to atypical conditions,
- Wide application in high-tech industry – they serve a role in hard drives, electric drive systems, precision medical tools, as well as technologically advanced constructions.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a strong case, which not only secures them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power 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
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of producing threads in the magnet and complicated shapes - preferred is a housing - magnet mounting.
- Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Additionally, small components of these magnets can disrupt the diagnostic process medical in case of swallowing.
- 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?
- using a base made of low-carbon steel, functioning as a magnetic yoke
- with a cross-section minimum 10 mm
- with a plane free of scratches
- under conditions of ideal adhesion (metal-to-metal)
- during detachment in a direction perpendicular to the plane
- at standard ambient temperature
Determinants of lifting force in real conditions
- Distance (between the magnet and the plate), because even a very small clearance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to varnish, rust or debris).
- Angle of force application – highest force is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Material type – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
- Base smoothness – the more even the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Temperature influence – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
Safe handling of NdFeB magnets
Metal Allergy
A percentage of the population suffer from a contact allergy to Ni, which is the common plating for neodymium magnets. Prolonged contact might lead to skin redness. It is best to use protective gloves.
Pacemakers
Warning for patients: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or ask another person to handle the magnets.
Caution required
Before starting, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Dust explosion hazard
Drilling and cutting of neodymium magnets carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Heat sensitivity
Keep cool. Neodymium magnets are susceptible to heat. If you need operation above 80°C, inquire about HT versions (H, SH, UH).
Swallowing risk
Only for adults. Tiny parts can be swallowed, causing intestinal necrosis. Keep away from children and animals.
GPS and phone interference
GPS units and smartphones are highly sensitive to magnetism. Close proximity with a strong magnet can ruin the sensors in your phone.
Magnetic media
Data protection: Neodymium magnets can ruin payment cards and delicate electronics (heart implants, hearing aids, mechanical watches).
Shattering risk
Watch out for shards. Magnets can explode upon violent connection, ejecting shards into the air. Eye protection is mandatory.
Hand protection
Watch your fingers. Two large magnets will snap together immediately with a force of massive weight, destroying anything in their path. Be careful!
