Strengths as well as weaknesses of rare earth magnets.
Strengths
- They retain full power for around ten years – the loss is just ~1% (based on simulations),
- They are resistant to demagnetization induced by external magnetic fields,
- The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to present itself better,
- They show high magnetic induction at the operating surface, which improves attraction properties,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of precise shaping and adjusting to precise conditions,
- Versatile presence in advanced technology sectors – they find application in computer drives, brushless drives, precision medical tools, as well as technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only protects them against impacts but also increases their durability
- Neodymium magnets lose their strength 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Limited ability of making nuts in the magnet and complex shapes - recommended is cover - magnetic holder.
- Health risk to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the context of child safety. Furthermore, small elements of these products can be problematic in diagnostics medical in case of swallowing.
- With budget limitations the cost of neodymium magnets is economically unviable,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what affects it?
- on a block made of structural steel, perfectly concentrating the magnetic field
- whose thickness equals approx. 10 mm
- characterized by smoothness
- under conditions of ideal adhesion (surface-to-surface)
- under vertical application of breakaway force (90-degree angle)
- at standard ambient temperature
What influences lifting capacity in practice
- Gap (betwixt the magnet and the plate), because even a microscopic clearance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, corrosion or dirt).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Base massiveness – too thin steel does not accept the full field, causing part of the flux to be wasted into the air.
- Metal type – not every steel attracts identically. Alloy additives weaken the attraction effect.
- Plate texture – ground elements ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
- Temperature – heating the magnet results in weakening of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity was assessed by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate reduces the holding force.
Warnings
Demagnetization risk
Standard neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. Damage is permanent.
Allergy Warning
Medical facts indicate that nickel (standard magnet coating) is a common allergen. If you have an allergy, avoid direct skin contact or select encased magnets.
Beware of splinters
Despite metallic appearance, the material is brittle and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Threat to electronics
Device Safety: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, medical aids, timepieces).
Medical interference
Warning for patients: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or ask another person to work with the magnets.
Fire warning
Combustion risk: Neodymium dust is explosive. Avoid machining magnets in home conditions as this risks ignition.
This is not a toy
Absolutely keep magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are tragic.
Hand protection
Big blocks can break fingers instantly. Do not put your hand between two strong magnets.
Powerful field
Handle magnets with awareness. Their huge power can surprise even experienced users. Plan your moves and do not underestimate their power.
Threat to navigation
GPS units and mobile phones are highly sensitive to magnetism. Close proximity with a strong magnet can permanently damage the sensors in your phone.
