Strengths and weaknesses of rare earth magnets.
Strengths
- They have constant strength, and over around ten years their performance decreases symbolically – ~1% (according to theory),
- They retain their magnetic properties even under close interference source,
- Thanks to the reflective finish, the plating of Ni-Cu-Ni, gold, or silver gives an clean appearance,
- The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures approaching 230°C and above...
- Possibility of detailed shaping as well as adjusting to atypical conditions,
- Huge importance in modern industrial fields – they are used in mass storage devices, drive modules, diagnostic systems, and modern systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a steel housing, which not only protects them against impacts but also raises their durability
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- We recommend a housing - magnetic mount, due to difficulties in producing nuts inside the magnet and complicated forms.
- Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, tiny parts of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Magnetic strength at its maximum – what it depends on?
- on a plate made of mild steel, perfectly concentrating the magnetic field
- whose thickness equals approx. 10 mm
- characterized by even structure
- under conditions of no distance (surface-to-surface)
- during detachment in a direction vertical to the plane
- in stable room temperature
Magnet lifting force in use – key factors
- Gap between magnet and steel – every millimeter of separation (caused e.g. by varnish or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Steel thickness – too thin steel causes magnetic saturation, causing part of the power to be wasted into the air.
- Plate material – low-carbon steel attracts best. Higher carbon content lower magnetic permeability and holding force.
- Surface condition – smooth surfaces ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
- Temperature influence – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under parallel forces the holding force is lower. In addition, even a small distance between the magnet and the plate lowers the lifting capacity.
Warnings
Immense force
Before starting, read the rules. Sudden snapping can break the magnet or hurt your hand. Be predictive.
Pinching danger
Large magnets can smash fingers instantly. Never put your hand between two attracting surfaces.
Impact on smartphones
GPS units and mobile phones are extremely sensitive to magnetic fields. Close proximity with a strong magnet can ruin the internal compass in your phone.
Do not drill into magnets
Machining of NdFeB material carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Electronic devices
Device Safety: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).
Do not overheat magnets
Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Fragile material
Watch out for shards. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
Pacemakers
For implant holders: Powerful magnets affect medical devices. Maintain minimum 30 cm distance or request help to handle the magnets.
Warning for allergy sufferers
Certain individuals suffer from a contact allergy to Ni, which is the common plating for neodymium magnets. Frequent touching might lead to a rash. We strongly advise use safety gloves.
Danger to the youngest
Strictly keep magnets out of reach of children. Choking hazard is high, and the consequences of magnets clamping inside the body are life-threatening.
