Pros and cons of rare earth magnets.
Strengths
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
- They are resistant to demagnetization induced by external magnetic fields,
- Thanks to the shimmering finish, the plating of nickel, gold, or silver gives an professional appearance,
- Neodymium magnets generate maximum magnetic induction on a small area, which allows for strong attraction,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- In view of the option of precise forming and adaptation to specialized solutions, neodymium magnets can be modeled in a variety of shapes and sizes, which amplifies use scope,
- Versatile presence in modern industrial fields – they are commonly used in mass storage devices, electromotive mechanisms, diagnostic systems, and industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also increases their durability
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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 very resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Limited possibility of making nuts in the magnet and complicated forms - preferred is a housing - magnet mounting.
- Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the context of child health protection. Additionally, small components of these products are able to disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Highest magnetic holding force – what it depends on?
- using a sheet made of high-permeability steel, acting as a ideal flux conductor
- with a thickness of at least 10 mm
- with a surface perfectly flat
- under conditions of ideal adhesion (metal-to-metal)
- during pulling in a direction vertical to the mounting surface
- in temp. approx. 20°C
Determinants of lifting force in real conditions
- Distance (between the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Angle of force application – maximum parameter is reached only during pulling at a 90° angle. The force required to slide of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Material type – the best choice is high-permeability steel. Hardened steels may generate lower lifting capacity.
- Smoothness – full contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, whereas under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.
Warnings
Warning for heart patients
Health Alert: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
GPS Danger
GPS units and smartphones are extremely susceptible to magnetism. Close proximity with a strong magnet can decalibrate the sensors in your phone.
Eye protection
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets leads to them shattering into small pieces.
Physical harm
Pinching hazard: The pulling power is so immense that it can cause blood blisters, pinching, and broken bones. Protective gloves are recommended.
Thermal limits
Control the heat. Exposing the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.
Handling guide
Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
No play value
Adult use only. Small elements pose a choking risk, causing serious injuries. Store out of reach of children and animals.
Cards and drives
Powerful magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.
Metal Allergy
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If skin irritation occurs, immediately stop working with magnets and wear gloves.
Machining danger
Combustion risk: Rare earth powder is explosive. Do not process magnets in home conditions as this risks ignition.
