Other products
Pros as well as cons of rare earth magnets.
Advantages
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (based on calculations),
- They do not lose their magnetic properties even under external field action,
- A magnet with a shiny nickel surface has an effective appearance,
- Neodymium magnets achieve maximum magnetic induction on a small surface, which increases force concentration,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures reaching 230°C and above...
- Possibility of custom creating as well as adapting to concrete conditions,
- Versatile presence in electronics industry – they are utilized in computer drives, electromotive mechanisms, medical devices, and modern systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
- Neodymium magnets decrease their power 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
- They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited possibility of creating nuts in the magnet and complicated forms - recommended is a housing - mounting mechanism.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Furthermore, tiny parts of these products can complicate diagnosis medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Detachment force of the magnet in optimal conditions – what affects it?
- with the use of a sheet made of special test steel, ensuring maximum field concentration
- possessing a thickness of minimum 10 mm to avoid saturation
- characterized by even structure
- with total lack of distance (no impurities)
- during pulling in a direction perpendicular to the mounting surface
- at temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Distance (between the magnet and the metal), because even a microscopic distance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to varnish, rust or dirt).
- Angle of force application – highest force is reached only during perpendicular pulling. The resistance to sliding of the magnet along the surface is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Steel grade – ideal substrate is pure iron steel. Cast iron may have worse magnetic properties.
- Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Temperature – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity was determined using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
H&S for magnets
Do not underestimate power
Before use, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
Danger to the youngest
Absolutely store magnets away from children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are life-threatening.
Dust explosion hazard
Dust created during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Keep away from computers
Data protection: Neodymium magnets can damage payment cards and sensitive devices (pacemakers, medical aids, mechanical watches).
Implant safety
Health Alert: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Risk of cracking
Watch out for shards. Magnets can fracture upon violent connection, launching shards into the air. Wear goggles.
Crushing risk
Protect your hands. Two powerful magnets will snap together instantly with a force of massive weight, destroying anything in their path. Exercise extreme caution!
Phone sensors
GPS units and smartphones are extremely susceptible to magnetism. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Operating temperature
Regular neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. Damage is permanent.
Sensitization to coating
Some people suffer from a sensitization to Ni, which is the typical protective layer for neodymium magnets. Frequent touching can result in an allergic reaction. We strongly advise wear safety gloves.
