Pros as well as cons of rare earth magnets.
Strengths
- They retain attractive force for almost ten years – the drop is just ~1% (according to analyses),
- Magnets effectively resist against loss of magnetization caused by ambient magnetic noise,
- In other words, due to the metallic finish of gold, the element gains a professional look,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a distinguishing feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of custom creating and modifying to specific requirements,
- Key role in future technologies – they are commonly used in hard drives, electric motors, precision medical tools, as well as complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- We suggest a housing - magnetic mount, due to difficulties in creating nuts inside the magnet and complicated forms.
- Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small elements of these magnets can disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Detachment force of the magnet in optimal conditions – what affects it?
- on a plate made of mild steel, optimally conducting the magnetic flux
- possessing a thickness of at least 10 mm to avoid saturation
- characterized by lack of roughness
- under conditions of gap-free contact (surface-to-surface)
- under axial application of breakaway force (90-degree angle)
- in neutral thermal conditions
Determinants of practical lifting force of a magnet
- Clearance – the presence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Material composition – different alloys reacts the same. Alloy additives weaken the attraction effect.
- Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, reducing force.
- Temperature – heating the magnet results in weakening of induction. Check the thermal limit for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate lowers the holding force.
H&S for magnets
Handling guide
Handle with care. Neodymium magnets attract from a long distance and connect with massive power, often faster than you can move away.
Fire warning
Combustion risk: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.
Impact on smartphones
Be aware: neodymium magnets produce a field that disrupts precision electronics. Keep a safe distance from your mobile, device, and navigation systems.
Do not overheat magnets
Standard neodymium magnets (N-type) lose power when the temperature exceeds 80°C. This process is irreversible.
Pacemakers
Patients with a ICD must keep an safe separation from magnets. The magnetic field can disrupt the functioning of the implant.
Keep away from children
These products are not suitable for play. Accidental ingestion of a few magnets can lead to them pinching intestinal walls, which constitutes a direct threat to life and necessitates immediate surgery.
Eye protection
Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Cards and drives
Data protection: Neodymium magnets can damage payment cards and sensitive devices (heart implants, medical aids, mechanical watches).
Allergy Warning
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If skin irritation appears, immediately stop handling magnets and wear gloves.
Bone fractures
Watch your fingers. Two powerful magnets will snap together instantly with a force of massive weight, crushing everything in their path. Exercise extreme caution!
