Pros as well as cons of Nd2Fe14B magnets.
Strengths
- They do not lose strength, even during approximately ten years – the decrease in lifting capacity is only ~1% (theoretically),
- They retain their magnetic properties even under close interference source,
- By applying a decorative layer of gold, the element acquires an nice look,
- Magnetic induction on the working part of the magnet remains very high,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Thanks to freedom in forming and the capacity to adapt to individual projects,
- Universal use in modern industrial fields – they are used in data components, electromotive mechanisms, advanced medical instruments, also other advanced devices.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its 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 and 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. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- We recommend casing - magnetic mount, due to difficulties in producing threads inside the magnet and complicated forms.
- Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which gains importance in the context of child safety. It is also worth noting that small components of these devices can disrupt the diagnostic process medical after entering the body.
- With large orders the cost of neodymium magnets is a challenge,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what it depends on?
- using a plate made of mild steel, acting as a ideal flux conductor
- with a cross-section minimum 10 mm
- with an ideally smooth contact surface
- with zero gap (without impurities)
- during pulling in a direction vertical to the plane
- at room temperature
Lifting capacity in practice – influencing factors
- Clearance – the presence of foreign body (paint, tape, gap) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds much less (often approx. 20-30% of nominal force).
- Plate thickness – insufficiently thick sheet does not close the flux, causing part of the power to be escaped to the other side.
- Material type – the best choice is high-permeability steel. Cast iron may have worse magnetic properties.
- Surface structure – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Temperature – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under shearing force the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate reduces the holding force.
Warnings
Protect data
Data protection: Neodymium magnets can damage payment cards and sensitive devices (pacemakers, hearing aids, mechanical watches).
Eye protection
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets will cause them breaking into small pieces.
Operating temperature
Do not overheat. NdFeB magnets are susceptible to heat. If you require operation above 80°C, look for HT versions (H, SH, UH).
Powerful field
Before starting, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Pinching danger
Watch your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!
Medical implants
Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Keep away from electronics
Navigation devices and mobile phones are extremely sensitive to magnetism. Close proximity with a strong magnet can decalibrate the internal compass in your phone.
Avoid contact if allergic
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction occurs, cease working with magnets and wear gloves.
No play value
Always keep magnets away from children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are very dangerous.
Dust is flammable
Combustion risk: Rare earth powder is explosive. Avoid machining magnets without safety gear as this may cause fire.
