Pros as well as cons of Nd2Fe14B magnets.
Pros
- They do not lose strength, even over approximately 10 years – the drop in lifting capacity is only ~1% (according to tests),
- Magnets effectively resist against loss of magnetization caused by ambient magnetic noise,
- Thanks to the smooth finish, the plating of Ni-Cu-Ni, gold-plated, or silver-plated gives an aesthetic appearance,
- Magnets exhibit exceptionally strong magnetic induction on the outer side,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Possibility of individual shaping as well as adjusting to defined needs,
- Huge importance in high-tech industry – they serve a role in HDD drives, electric motors, medical equipment, as well as modern systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We suggest cover - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complex forms.
- Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these magnets are able to be problematic in diagnostics medical when they are in the body.
- With mass production the cost of neodymium magnets is a challenge,
Pull force analysis
Maximum lifting force for a neodymium magnet – what it depends on?
- using a sheet made of low-carbon steel, serving as a circuit closing element
- whose thickness is min. 10 mm
- characterized by even structure
- with total lack of distance (no paint)
- for force acting at a right angle (in the magnet axis)
- at room temperature
Lifting capacity in real conditions – factors
- Gap (between the magnet and the plate), as even a microscopic distance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Direction of force – maximum parameter is reached only during perpendicular pulling. The resistance to sliding of the magnet along the surface is standardly many times lower (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 generating force.
- Steel type – low-carbon steel gives the best results. Alloy admixtures lower magnetic properties and holding force.
- Surface structure – the more even the surface, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was determined using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
Conscious usage
Exercise caution. Rare earth magnets attract from a distance and connect with huge force, often quicker than you can move away.
Risk of cracking
Beware of splinters. Magnets can explode upon violent connection, ejecting shards into the air. Wear goggles.
Combustion hazard
Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
Nickel allergy
Medical facts indicate that the nickel plating (standard magnet coating) is a potent allergen. For allergy sufferers, refrain from touching magnets with bare hands and opt for versions in plastic housing.
Power loss in heat
Control the heat. Heating the magnet to high heat will destroy its properties and strength.
Crushing risk
Large magnets can smash fingers instantly. Do not place your hand between two strong magnets.
Adults only
Product intended for adults. Tiny parts pose a choking risk, causing serious injuries. Store out of reach of kids and pets.
Electronic devices
Powerful magnetic fields can destroy records on payment cards, hard drives, and storage devices. Stay away of min. 10 cm.
Pacemakers
Patients with a pacemaker should maintain an safe separation from magnets. The magnetism can stop the operation of the implant.
GPS and phone interference
Navigation devices and mobile phones are highly sensitive to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.
