Advantages as well as disadvantages of Nd2Fe14B magnets.
Benefits
- Their power is durable, and after around 10 years it decreases only by ~1% (theoretically),
- They are extremely resistant to demagnetization induced by external magnetic fields,
- A magnet with a metallic nickel surface looks better,
- Magnets possess huge magnetic induction on the active area,
- 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...
- Possibility of accurate machining and adjusting to precise conditions,
- Versatile presence in future technologies – they are commonly used in hard drives, brushless drives, diagnostic systems, as well as technologically advanced constructions.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Weaknesses
- At strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Due to limitations in realizing nuts and complex forms in magnets, we recommend using a housing - magnetic holder.
- Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets are able to complicate diagnosis medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Best holding force of the magnet in ideal parameters – what affects it?
- using a base made of high-permeability steel, functioning as a ideal flux conductor
- with a thickness minimum 10 mm
- with a surface free of scratches
- with zero gap (no paint)
- during pulling in a direction vertical to the plane
- at ambient temperature approx. 20 degrees Celsius
Practical lifting capacity: influencing factors
- Clearance – existence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is obtained only during perpendicular pulling. The shear force of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Steel grade – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
- Surface quality – the more even the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Safety rules for work with NdFeB magnets
Thermal limits
Watch the temperature. Heating the magnet to high heat will destroy its properties and strength.
Eye protection
NdFeB magnets are ceramic materials, which means they are very brittle. Clashing of two magnets will cause them breaking into shards.
Threat to electronics
Data protection: Strong magnets can damage payment cards and delicate electronics (pacemakers, hearing aids, timepieces).
Do not drill into magnets
Dust generated during cutting of magnets is combustible. Do not drill into magnets unless you are an expert.
Pacemakers
Patients with a ICD have to keep an absolute distance from magnets. The magnetism can interfere with the functioning of the implant.
Impact on smartphones
Navigation devices and smartphones are highly sensitive to magnetism. Direct contact with a strong magnet can decalibrate the sensors in your phone.
No play value
Absolutely store magnets away from children. Ingestion danger is high, and the effects of magnets connecting inside the body are fatal.
Handling rules
Use magnets with awareness. Their huge power can shock even experienced users. Plan your moves and respect their power.
Avoid contact if allergic
Certain individuals experience a sensitization to Ni, which is the common plating for NdFeB magnets. Prolonged contact might lead to skin redness. We strongly advise wear protective gloves.
Bodily injuries
Protect your hands. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Be careful!
