Pros as well as cons of neodymium magnets.

Strengths

Besides their stability, neodymium magnets are valued for these benefits:
  • They do not lose power, even after approximately ten years – the reduction in power is only ~1% (based on measurements),
  • They retain their magnetic properties even under external field action,
  • By covering with a lustrous coating of silver, the element acquires an professional look,
  • Neodymium magnets deliver maximum magnetic induction on a contact point, which ensures high operational effectiveness,
  • Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures approaching 230°C and above...
  • Thanks to freedom in shaping and the ability to customize to client solutions,
  • Key role in high-tech industry – they are utilized in computer drives, electric motors, precision medical tools, and multitasking production systems.
  • Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Disadvantages

Problematic aspects of neodymium magnets: tips and applications.
  • At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as 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 suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
  • Limited ability of producing threads in the magnet and complicated forms - recommended is casing - magnet mounting.
  • Health risk resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these devices can disrupt the diagnostic process medical in case of swallowing.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Highest magnetic holding force – what it depends on?

The force parameter is a measurement result conducted under standard conditions:
  • on a base made of mild steel, optimally conducting the magnetic field
  • whose transverse dimension equals approx. 10 mm
  • characterized by even structure
  • without any insulating layer between the magnet and steel
  • during detachment in a direction perpendicular to the plane
  • in neutral thermal conditions

Determinants of lifting force in real conditions

Bear in mind that the working load will differ depending on elements below, in order of importance:
  • Distance – the presence of any layer (rust, tape, air) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
  • Direction of force – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
  • Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
  • Chemical composition of the base – low-carbon steel gives the best results. Alloy admixtures lower magnetic permeability and lifting capacity.
  • Base smoothness – the more even the surface, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
  • Thermal factor – hot environment weakens magnetic field. Too high temperature can permanently demagnetize the magnet.

Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas 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 holding force.

H&S for magnets
GPS and phone interference

Note: rare earth magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your phone, device, and navigation systems.

Respect the power

Use magnets with awareness. Their immense force can shock even experienced users. Plan your moves and respect their power.

Adults only

These products are not toys. Accidental ingestion of several magnets can lead to them attracting across intestines, which poses a severe health hazard and requires immediate surgery.

Sensitization to coating

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction occurs, cease working with magnets and use protective gear.

ICD Warning

For implant holders: Powerful magnets affect medical devices. Keep minimum 30 cm distance or request help to handle the magnets.

Crushing force

Watch your fingers. Two large magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Be careful!

Magnets are brittle

Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Wear goggles.

Power loss in heat

Keep cool. NdFeB magnets are sensitive to temperature. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).

Threat to electronics

Do not bring magnets close to a purse, computer, or screen. The magnetic field can permanently damage these devices and erase data from cards.

Dust explosion hazard

Machining of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
