Pros as well as cons of rare earth magnets.
Benefits
- They retain attractive force for around 10 years – the drop is just ~1% (based on simulations),
- They feature excellent resistance to weakening of magnetic properties as a result of opposing magnetic fields,
- Thanks to the smooth finish, the plating of nickel, gold-plated, or silver-plated gives an visually attractive appearance,
- Neodymium magnets create maximum magnetic induction on a small area, which increases force concentration,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Considering the ability of accurate molding and adaptation to individualized needs, NdFeB magnets can be modeled in a wide range of shapes and sizes, which amplifies use scope,
- Significant place in electronics industry – they are used in computer drives, electric drive systems, precision medical tools, as well as other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a special holder, which not only protects them against impacts but also raises their durability
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- 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 and corrosion.
- Limited ability of producing nuts in the magnet and complicated forms - preferred is a housing - mounting mechanism.
- Possible danger resulting from small fragments of magnets are risky, if swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these devices 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
Highest magnetic holding force – what it depends on?
- on a block made of structural steel, effectively closing the magnetic field
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- with an ground touching surface
- with total lack of distance (without impurities)
- for force applied at a right angle (in the magnet axis)
- in temp. approx. 20°C
Lifting capacity in real conditions – factors
- Gap between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Steel thickness – too thin plate does not accept the full field, causing part of the flux to be escaped into the air.
- Metal type – not every steel reacts the same. High carbon content weaken the attraction effect.
- Surface structure – the more even the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, in contrast under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a small distance between the magnet and the plate reduces the lifting capacity.
Precautions when working with NdFeB magnets
Demagnetization risk
Control the heat. Heating the magnet above 80 degrees Celsius will ruin its properties and strength.
Crushing risk
Big blocks can break fingers instantly. Do not put your hand betwixt two strong magnets.
Magnetic interference
Be aware: rare earth magnets generate a field that disrupts precision electronics. Keep a separation from your phone, device, and GPS.
Warning for heart patients
People with a pacemaker should keep an safe separation from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Powerful field
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Dust is flammable
Fire warning: Neodymium dust is explosive. Avoid machining magnets without safety gear as this may cause fire.
Keep away from computers
Do not bring magnets close to a wallet, computer, or screen. The magnetic field can destroy these devices and wipe information from cards.
Allergic reactions
A percentage of the population experience a contact allergy to Ni, which is the standard coating for neodymium magnets. Frequent touching might lead to a rash. We strongly advise use safety gloves.
Beware of splinters
Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
No play value
Always keep magnets out of reach of children. Choking hazard is high, and the effects of magnets clamping inside the body are tragic.
