Pros and cons of neodymium magnets.
Advantages
- They retain attractive force for nearly 10 years – the loss is just ~1% (in theory),
- They retain their magnetic properties even under external field action,
- Thanks to the elegant finish, the coating of Ni-Cu-Ni, gold-plated, or silver-plated gives an modern appearance,
- They show high magnetic induction at the operating surface, making them more effective,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures reaching 230°C and above...
- Thanks to the option of precise forming and customization to specialized requirements, magnetic components can be modeled in a variety of forms and dimensions, which amplifies use scope,
- Universal use in electronics industry – they are utilized in HDD drives, electromotive mechanisms, medical devices, and multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Cons
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength 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
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of creating threads in the magnet and complex shapes - recommended is cover - magnetic holder.
- Health risk related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child safety. It is also worth noting that tiny parts of these magnets are able to be problematic in diagnostics medical when they are in the body.
- With large orders the cost of neodymium magnets can be a barrier,
Holding force characteristics
Magnetic strength at its maximum – what affects it?
- with the use of a yoke made of special test steel, guaranteeing maximum field concentration
- whose thickness is min. 10 mm
- with a plane cleaned and smooth
- under conditions of gap-free contact (surface-to-surface)
- for force acting at a right angle (pull-off, not shear)
- at standard ambient temperature
Lifting capacity in practice – influencing factors
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Angle of force application – maximum parameter is reached only during perpendicular pulling. The shear force of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick steel causes magnetic saturation, causing part of the flux to be wasted into the air.
- Metal type – not every steel attracts identically. High carbon content worsen the attraction effect.
- Base smoothness – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Thermal factor – high temperature weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was determined using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet and the plate lowers the holding force.
H&S for magnets
Handling rules
Handle magnets consciously. Their huge power can surprise even experienced users. Plan your moves and do not underestimate their force.
Do not give to children
Strictly keep magnets out of reach of children. Choking hazard is high, and the effects of magnets connecting inside the body are tragic.
Metal Allergy
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction appears, cease handling magnets and use protective gear.
Dust is flammable
Drilling and cutting of neodymium magnets carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Threat to navigation
A strong magnetic field negatively affects the operation of magnetometers in phones and GPS navigation. Keep magnets close to a smartphone to prevent breaking the sensors.
Hand protection
Risk of injury: The attraction force is so immense that it can result in blood blisters, pinching, and broken bones. Protective gloves are recommended.
Fragile material
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.
Threat to electronics
Do not bring magnets close to a wallet, laptop, or screen. The magnetism can destroy these devices and erase data from cards.
Danger to pacemakers
Patients with a ICD have to maintain an absolute distance from magnets. The magnetic field can disrupt the functioning of the implant.
Power loss in heat
Control the heat. Heating the magnet to high heat will ruin its magnetic structure and strength.
