Pros as well as cons of rare earth magnets.
Benefits
- They do not lose magnetism, even over nearly 10 years – the decrease in power is only ~1% (based on measurements),
- Magnets very well defend themselves against loss of magnetization caused by ambient magnetic noise,
- A magnet with a metallic silver surface looks better,
- Magnetic induction on the surface of the magnet remains exceptional,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Possibility of accurate creating and adapting to concrete requirements,
- Fundamental importance in modern technologies – they are used in mass storage devices, electric motors, medical equipment, and multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Cons
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited possibility of creating nuts in the magnet and complicated shapes - preferred is casing - magnetic holder.
- Potential hazard related to microscopic parts of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these devices are able to be problematic in diagnostics medical in case of swallowing.
- Due to expensive raw materials, their price is relatively high,
Pull force analysis
Maximum lifting capacity of the magnet – what affects it?
- with the contact of a yoke made of low-carbon steel, ensuring full magnetic saturation
- whose thickness reaches at least 10 mm
- with a plane cleaned and smooth
- without any insulating layer between the magnet and steel
- under perpendicular force direction (90-degree angle)
- in neutral thermal conditions
Practical lifting capacity: influencing factors
- Distance – existence of foreign body (rust, dirt, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Base massiveness – insufficiently thick sheet does not close the flux, causing part of the flux to be wasted to the other side.
- Steel grade – the best choice is high-permeability steel. Stainless steels may have worse magnetic properties.
- Smoothness – full contact is possible only on polished steel. Rough texture reduce the real contact area, reducing force.
- Temperature – temperature increase causes a temporary drop of force. Check the thermal limit for a given model.
Lifting capacity was determined using a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate decreases the holding force.
Safety rules for work with neodymium magnets
Combustion hazard
Fire hazard: Rare earth powder is explosive. Avoid machining magnets without safety gear as this may cause fire.
Protective goggles
Despite the nickel coating, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Pacemakers
Patients with a pacemaker must maintain an large gap from magnets. The magnetism can interfere with the operation of the life-saving device.
Avoid contact if allergic
Some people experience a hypersensitivity to nickel, which is the typical protective layer for NdFeB magnets. Extended handling may cause dermatitis. We strongly advise wear safety gloves.
Power loss in heat
Do not overheat. Neodymium magnets are susceptible to temperature. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Powerful field
Before starting, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Keep away from computers
Intense magnetic fields can destroy records on payment cards, hard drives, and storage devices. Stay away of at least 10 cm.
Finger safety
Large magnets can break fingers in a fraction of a second. Under no circumstances put your hand between two strong magnets.
Phone sensors
Remember: neodymium magnets produce a field that confuses sensitive sensors. Maintain a separation from your phone, tablet, and GPS.
Product not for children
Only for adults. Tiny parts can be swallowed, causing intestinal necrosis. Store away from children and animals.
