Pros as well as cons of rare earth magnets.
Strengths
- They retain magnetic properties for almost 10 years – the drop is just ~1% (in theory),
- Magnets very well protect themselves against demagnetization caused by external fields,
- In other words, due to the reflective surface of silver, the element gains visual value,
- Neodymium magnets deliver maximum magnetic induction on a contact point, which ensures high operational effectiveness,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures approaching 230°C and above...
- Thanks to the ability of flexible forming and customization to individualized requirements, neodymium magnets can be produced in a variety of shapes and sizes, which makes them more universal,
- Huge importance in electronics industry – they are utilized in data components, drive modules, precision medical tools, and complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- At strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited possibility of making nuts in the magnet and complicated forms - recommended is casing - magnet mounting.
- Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child health protection. Additionally, small components of these devices can disrupt the diagnostic process medical in case of swallowing.
- Due to neodymium price, their price is relatively high,
Pull force analysis
Detachment force of the magnet in optimal conditions – what affects it?
- with the use of a yoke made of low-carbon steel, ensuring maximum field concentration
- whose transverse dimension equals approx. 10 mm
- with an ground touching surface
- without any clearance between the magnet and steel
- under vertical application of breakaway force (90-degree angle)
- at temperature room level
Determinants of practical lifting force of a magnet
- Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys attracts identically. High carbon content worsen the interaction with the magnet.
- Plate texture – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces weaken the grip.
- Thermal environment – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
Warnings
Crushing risk
Danger of trauma: The pulling power is so immense that it can cause blood blisters, pinching, and broken bones. Protective gloves are recommended.
Allergic reactions
Certain individuals experience a contact allergy to Ni, which is the common plating for NdFeB magnets. Frequent touching might lead to skin redness. We strongly advise wear safety gloves.
Handling guide
Handle magnets consciously. Their powerful strength can shock even professionals. Be vigilant and do not underestimate their force.
Eye protection
Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.
Compass and GPS
Be aware: neodymium magnets generate a field that confuses sensitive sensors. Maintain a separation from your mobile, device, and GPS.
Safe distance
Equipment safety: Strong magnets can damage data carriers and delicate electronics (pacemakers, medical aids, timepieces).
No play value
Only for adults. Tiny parts can be swallowed, causing intestinal necrosis. Store away from kids and pets.
Fire warning
Mechanical processing of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Danger to pacemakers
Warning for patients: Powerful magnets affect electronics. Maintain minimum 30 cm distance or request help to handle the magnets.
Maximum temperature
Regular neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. This process is irreversible.
