Pros as well as cons of Nd2Fe14B magnets.
Benefits
- They do not lose magnetism, even over around 10 years – the reduction in power is only ~1% (according to tests),
- They retain their magnetic properties even under close interference source,
- Thanks to the reflective finish, the layer of Ni-Cu-Ni, gold-plated, or silver-plated gives an professional appearance,
- Magnets have huge magnetic induction on the outer layer,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Due to the ability of flexible molding and adaptation to individualized projects, neodymium magnets can be created in a wide range of shapes and sizes, which increases their versatility,
- Wide application in electronics industry – they are utilized in mass storage devices, electromotive mechanisms, medical devices, also multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which allows their use in miniature devices
Cons
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- We suggest casing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complex forms.
- Health risk related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, small components of these products can disrupt the diagnostic process medical when they are in the body.
- Due to complex production process, their price is higher than average,
Holding force characteristics
Maximum magnetic pulling force – what affects it?
- on a base made of mild steel, perfectly concentrating the magnetic field
- with a cross-section no less than 10 mm
- with a surface cleaned and smooth
- under conditions of gap-free contact (metal-to-metal)
- under perpendicular force direction (90-degree angle)
- in temp. approx. 20°C
Lifting capacity in real conditions – factors
- Distance (between the magnet and the plate), because even a microscopic distance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Plate material – low-carbon steel gives the best results. Higher carbon content decrease magnetic permeability and lifting capacity.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Uneven metal weaken the grip.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was assessed with the use of a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate lowers the lifting capacity.
Warnings
Safe operation
Handle magnets consciously. Their powerful strength can surprise even professionals. Stay alert and respect their force.
Sensitization to coating
Some people have a contact allergy to nickel, which is the standard coating for neodymium magnets. Prolonged contact may cause dermatitis. We strongly advise wear protective gloves.
Fire warning
Mechanical processing of neodymium magnets carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Heat warning
Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. Damage is permanent.
No play value
NdFeB magnets are not suitable for play. Swallowing a few magnets can lead to them pinching intestinal walls, which constitutes a severe health hazard and requires immediate surgery.
Implant safety
Individuals with a ICD must maintain an safe separation from magnets. The magnetic field can stop the functioning of the life-saving device.
Precision electronics
GPS units and smartphones are extremely susceptible to magnetic fields. Direct contact with a strong magnet can ruin the internal compass in your phone.
Physical harm
Watch your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!
Protective goggles
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Safe distance
Avoid bringing magnets near a purse, laptop, or TV. The magnetism can permanently damage these devices and wipe information from cards.
