Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- Their magnetic field is maintained, and after approximately 10 years it decreases only by ~1% (theoretically),
- They do not lose their magnetic properties even under close interference source,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- They are known for high magnetic induction at the operating surface, which increases their power,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Thanks to versatility in forming and the capacity to modify to client solutions,
- Huge importance in future technologies – they are commonly used in magnetic memories, brushless drives, precision medical tools, also technologically advanced constructions.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's 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.
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of making nuts in the magnet and complex shapes - recommended is a housing - magnetic holder.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the context of child health protection. Furthermore, tiny parts of these devices are able to complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Magnetic strength at its maximum – what it depends on?
- with the contact of a sheet made of special test steel, ensuring maximum field concentration
- with a cross-section of at least 10 mm
- with an ideally smooth touching surface
- under conditions of no distance (surface-to-surface)
- under perpendicular force vector (90-degree angle)
- in stable room temperature
Impact of factors on magnetic holding capacity in practice
- Air gap (between the magnet and the metal), as even a tiny clearance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Metal type – not every steel reacts the same. High carbon content worsen the interaction with the magnet.
- Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, whereas under shearing force the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
H&S for magnets
Phone sensors
Note: rare earth magnets generate a field that interferes with precision electronics. Keep a safe distance from your phone, tablet, and navigation systems.
Power loss in heat
Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Material brittleness
Despite the nickel coating, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Warning for heart patients
Life threat: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
Do not give to children
Adult use only. Small elements pose a choking risk, causing severe trauma. Store out of reach of children and animals.
Skin irritation risks
Nickel alert: The nickel-copper-nickel coating contains nickel. If redness appears, immediately stop handling magnets and wear gloves.
Cards and drives
Equipment safety: Strong magnets can damage payment cards and delicate electronics (heart implants, medical aids, mechanical watches).
Machining danger
Fire warning: Neodymium dust is explosive. Avoid machining magnets in home conditions as this may cause fire.
Physical harm
Large magnets can smash fingers instantly. Under no circumstances put your hand between two strong magnets.
Handling guide
Before use, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
