Pros and cons of neodymium magnets.
Advantages
- They have unchanged lifting capacity, and over more than ten years their performance decreases symbolically – ~1% (according to theory),
- They maintain their magnetic properties even under strong external field,
- By covering with a decorative coating of nickel, the element presents an nice look,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of detailed shaping as well as optimizing to atypical applications,
- Fundamental importance in modern technologies – they find application in computer drives, electric motors, precision medical tools, as well as multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in compact constructions
Cons
- To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- We recommend cover - magnetic mount, due to difficulties in producing threads inside the magnet and complex forms.
- Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Furthermore, small components of these devices can be problematic in diagnostics medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum holding power of the magnet – what contributes to it?
- with the use of a yoke made of special test steel, ensuring maximum field concentration
- possessing a thickness of min. 10 mm to ensure full flux closure
- with an ideally smooth contact surface
- without any insulating layer between the magnet and steel
- during detachment in a direction perpendicular to the mounting surface
- in temp. approx. 20°C
Determinants of practical lifting force of a magnet
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Steel thickness – insufficiently thick steel does not accept the full field, causing part of the flux to be wasted to the other side.
- Metal type – different alloys attracts identically. High carbon content worsen the interaction with the magnet.
- Surface condition – ground elements ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
- Thermal factor – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, however under parallel forces the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
Warnings
Implant safety
Warning for patients: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or ask another person to work with the magnets.
Combustion hazard
Powder produced during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.
GPS Danger
A strong magnetic field disrupts the functioning of magnetometers in smartphones and GPS navigation. Keep magnets close to a device to prevent damaging the sensors.
Skin irritation risks
A percentage of the population experience a sensitization to nickel, which is the standard coating for neodymium magnets. Frequent touching can result in a rash. It is best to wear safety gloves.
Protect data
Do not bring magnets close to a purse, computer, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
Powerful field
Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
Magnets are brittle
Protect your eyes. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.
Serious injuries
Protect your hands. Two large magnets will snap together instantly with a force of massive weight, destroying everything in their path. Exercise extreme caution!
Swallowing risk
Strictly store magnets away from children. Ingestion danger is high, and the effects of magnets connecting inside the body are life-threatening.
Do not overheat magnets
Control the heat. Exposing the magnet to high heat will permanently weaken its properties and pulling force.
