Strengths as well as weaknesses of rare earth magnets.
Advantages
- They have constant strength, and over around 10 years their performance decreases symbolically – ~1% (in testing),
- Magnets perfectly defend themselves against loss of magnetization caused by ambient magnetic noise,
- Thanks to the elegant finish, the layer of Ni-Cu-Ni, gold-plated, or silver-plated gives an visually attractive appearance,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- 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...
- In view of the ability of accurate forming and customization to unique projects, neodymium magnets can be produced in a variety of shapes and sizes, which increases their versatility,
- Versatile presence in innovative solutions – they are commonly used in hard drives, electromotive mechanisms, diagnostic systems, and industrial machines.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a special holder, which not only protects them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets suffer a drop in force. 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
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- We recommend casing - magnetic holder, due to difficulties in creating nuts inside the magnet and complicated forms.
- Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these products can disrupt the diagnostic process medical in case of swallowing.
- With mass production the cost of neodymium magnets is economically unviable,
Holding force characteristics
Detachment force of the magnet in optimal conditions – what contributes to it?
- using a base made of high-permeability steel, acting as a ideal flux conductor
- with a thickness of at least 10 mm
- characterized by lack of roughness
- under conditions of ideal adhesion (surface-to-surface)
- under vertical force direction (90-degree angle)
- in temp. approx. 20°C
Magnet lifting force in use – key factors
- Distance – existence of any layer (paint, dirt, air) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Load vector – highest force is available only during perpendicular pulling. The shear force of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Steel type – mild steel attracts best. Higher carbon content reduce magnetic permeability and holding force.
- Base smoothness – the more even the surface, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Thermal factor – hot environment weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance between the magnet and the plate lowers the load capacity.
Heat sensitivity
Monitor thermal conditions. Heating the magnet to high heat will permanently weaken its properties and pulling force.
Material brittleness
NdFeB magnets are ceramic materials, which means they are very brittle. Clashing of two magnets leads to them cracking into shards.
Finger safety
Danger of trauma: The attraction force is so immense that it can cause hematomas, crushing, and even bone fractures. Protective gloves are recommended.
GPS and phone interference
A powerful magnetic field negatively affects the operation of compasses in phones and GPS navigation. Do not bring magnets close to a smartphone to prevent breaking the sensors.
Choking Hazard
Adult use only. Tiny parts can be swallowed, leading to intestinal necrosis. Keep away from kids and pets.
Conscious usage
Handle with care. Neodymium magnets attract from a long distance and connect with huge force, often quicker than you can move away.
Life threat
Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
Safe distance
Powerful magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.
Allergic reactions
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, immediately stop working with magnets and wear gloves.
Fire risk
Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
