Strengths as well as weaknesses of neodymium magnets.
Advantages
- They retain attractive force for nearly ten years – the drop is just ~1% (based on simulations),
- They do not lose their magnetic properties even under close interference source,
- Thanks to the metallic finish, the coating of nickel, gold-plated, or silver gives an elegant appearance,
- Magnets possess extremely high magnetic induction on the active area,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- In view of the possibility of free molding and customization to individualized needs, magnetic components can be manufactured in a variety of shapes and sizes, which increases their versatility,
- Wide application in modern industrial fields – they serve a role in computer drives, electric drive systems, medical equipment, also multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its 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 stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in realizing nuts and complex forms in magnets, we recommend using casing - magnetic mechanism.
- Possible danger to health – tiny shards of magnets are risky, in case of ingestion, which gains importance in the context of child health protection. Additionally, small elements of these magnets can disrupt the diagnostic process medical in case of swallowing.
- Due to complex production process, their price exceeds standard values,
Lifting parameters
Highest magnetic holding force – what affects it?
- with the use of a sheet made of low-carbon steel, ensuring full magnetic saturation
- whose thickness is min. 10 mm
- with a surface perfectly flat
- under conditions of gap-free contact (surface-to-surface)
- during pulling in a direction vertical to the mounting surface
- at room temperature
Lifting capacity in real conditions – factors
- Clearance – the presence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of maximum force).
- Steel thickness – insufficiently thick sheet causes magnetic saturation, causing part of the power to be lost into the air.
- Metal type – different alloys attracts identically. Alloy additives worsen the interaction with the magnet.
- Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal weaken the grip.
- Heat – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate lowers the load capacity.
Warnings
Sensitization to coating
A percentage of the population have a sensitization to Ni, which is the common plating for neodymium magnets. Frequent touching can result in a rash. We recommend use protective gloves.
Conscious usage
Before starting, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
Permanent damage
Control the heat. Heating the magnet above 80 degrees Celsius will destroy its properties and pulling force.
Pacemakers
Patients with a ICD have to maintain an large gap from magnets. The magnetic field can interfere with the functioning of the life-saving device.
Risk of cracking
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Threat to electronics
Equipment safety: Strong magnets can damage data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).
No play value
Strictly store magnets away from children. Choking hazard is significant, and the consequences of magnets clamping inside the body are fatal.
Magnetic interference
Navigation devices and smartphones are extremely susceptible to magnetism. Direct contact with a strong magnet can ruin the internal compass in your phone.
Fire risk
Powder produced during cutting of magnets is flammable. Avoid drilling into magnets unless you are an expert.
Physical harm
Big blocks can break fingers in a fraction of a second. Do not put your hand between two strong magnets.
