Advantages as well as disadvantages of neodymium magnets.
Advantages
- They have unchanged lifting capacity, and over around 10 years their attraction force decreases symbolically – ~1% (according to theory),
- They do not lose their magnetic properties even under close interference source,
- In other words, due to the metallic surface of silver, the element looks attractive,
- Magnets have huge magnetic induction on the surface,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- In view of the option of precise forming and adaptation to individualized needs, magnetic components can be modeled in a broad palette of shapes and sizes, which amplifies use scope,
- Fundamental importance in future technologies – they serve a role in computer drives, electric drive systems, advanced medical instruments, and technologically advanced constructions.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- Limited ability of making nuts in the magnet and complex forms - recommended is cover - magnetic holder.
- Health risk to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the context of child safety. Furthermore, small elements of these magnets are able to complicate diagnosis medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what it depends on?
- on a plate made of structural steel, effectively closing the magnetic flux
- with a thickness minimum 10 mm
- characterized by smoothness
- with direct contact (without coatings)
- during pulling in a direction perpendicular to the plane
- in temp. approx. 20°C
Lifting capacity in practice – influencing factors
- Clearance – existence of foreign body (rust, tape, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Angle of force application – highest force is available only during perpendicular pulling. The resistance to sliding of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick plate does not close the flux, causing part of the power to be lost to the other side.
- Steel grade – the best choice is pure iron steel. Cast iron may attract less.
- Surface quality – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Thermal environment – temperature increase results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity was measured with the use of a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate reduces the lifting capacity.
Precautions when working with NdFeB magnets
Metal Allergy
A percentage of the population experience a contact allergy to Ni, which is the common plating for neodymium magnets. Frequent touching may cause dermatitis. We suggest use safety gloves.
Crushing force
Watch your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Medical interference
Health Alert: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Protective goggles
Despite metallic appearance, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
Phone sensors
A strong magnetic field disrupts the functioning of compasses in smartphones and GPS navigation. Do not bring magnets near a smartphone to avoid damaging the sensors.
Swallowing risk
Adult use only. Tiny parts can be swallowed, leading to serious injuries. Keep out of reach of children and animals.
Fire warning
Powder generated during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Protect data
Avoid bringing magnets near a purse, computer, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.
Permanent damage
Monitor thermal conditions. Heating the magnet to high heat will destroy its properties and strength.
Do not underestimate power
Be careful. Rare earth magnets act from a long distance and connect with huge force, often quicker than you can react.
