Strengths as well as weaknesses of rare earth magnets.
Strengths
- Their magnetic field remains stable, and after around ten years it drops only by ~1% (theoretically),
- They are noted for resistance to demagnetization induced by presence of other magnetic fields,
- In other words, due to the shiny layer of gold, the element gains a professional look,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Thanks to freedom in shaping and the capacity to customize to individual projects,
- Versatile presence in modern industrial fields – they are used in magnetic memories, motor assemblies, diagnostic systems, as well as multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Disadvantages
- At very strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in creating threads and complex forms in magnets, we recommend using cover - magnetic mount.
- Health risk related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, small components of these devices are able to complicate diagnosis medical after entering the body.
- Due to expensive raw materials, their price is higher than average,
Holding force characteristics
Detachment force of the magnet in optimal conditions – what affects it?
- with the application of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- whose transverse dimension is min. 10 mm
- with a surface free of scratches
- with direct contact (without paint)
- during detachment in a direction perpendicular to the mounting surface
- at ambient temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Plate material – low-carbon steel attracts best. Higher carbon content reduce magnetic permeability and holding force.
- Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal weaken the grip.
- Temperature – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under shearing force the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
Safe handling of NdFeB magnets
Protective goggles
NdFeB magnets are sintered ceramics, which means they are very brittle. Impact of two magnets leads to them breaking into small pieces.
Bodily injuries
Protect your hands. Two large magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
Electronic devices
Avoid bringing magnets near a wallet, laptop, or screen. The magnetism can permanently damage these devices and wipe information from cards.
Handling rules
Use magnets consciously. Their huge power can surprise even professionals. Stay alert and do not underestimate their power.
Maximum temperature
Standard neodymium magnets (grade N) lose power when the temperature goes above 80°C. The loss of strength is permanent.
Combustion hazard
Fire warning: Rare earth powder is highly flammable. Do not process magnets without safety gear as this may cause fire.
GPS Danger
A powerful magnetic field negatively affects the functioning of magnetometers in smartphones and navigation systems. Do not bring magnets near a smartphone to avoid damaging the sensors.
Medical implants
Warning for patients: Powerful magnets disrupt electronics. Maintain at least 30 cm distance or ask another person to work with the magnets.
Allergy Warning
A percentage of the population experience a hypersensitivity to nickel, which is the standard coating for NdFeB magnets. Frequent touching can result in an allergic reaction. We strongly advise use protective gloves.
Swallowing risk
Only for adults. Small elements can be swallowed, causing serious injuries. Keep out of reach of kids and pets.
