Magnetic Induction

Other offers

A manual separator is a basic tool for quick identification and sorting of metals. It allows checking if a given item is ferromagnetic (steel, cast iron) or not (aluminum, copper, stainless steel). It is also useful for pulling small steel elements from crates, ash, sand, or sawdust.
The magnet "catches" iron but remains completely indifferent to aluminum, copper, brass, and zinc. This is the simplest and fastest test to distinguish valuable non-ferrous metals from cheap steel.
Neodymiums are more compact and effective during all-day work at a scrap yard. Strong neodymium field detects even weakly magnetic alloys and contaminants. The neodymium version is currently the standard in professional scrap yards.
The construction consists of a hermetic can protecting the magnet and an ergonomic handle. The grip was designed so as not to slip in the hand, even in a work glove. Thanks to such an armored build, the separator is resistant to difficult conditions prevailing at a scrap yard.
Standard manual separators (such as SMZR 32x175 / N52) do not have a release mechanism and require manual cleaning. We also offer versions where pulling the handle automatically drops collected material. The sliding technique is more effective and requires less force than perpendicular tearing.

Advantages as well as disadvantages of neodymium magnets.

Advantages

Besides their immense field intensity, neodymium magnets offer the following advantages:
  • They retain full power for around ten years – the drop is just ~1% (according to analyses),
  • Neodymium magnets are characterized by extremely resistant to magnetic field loss caused by external interference,
  • A magnet with a shiny silver surface looks better,
  • Neodymium magnets create maximum magnetic induction on a small surface, which ensures high operational effectiveness,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
  • In view of the ability of precise forming and customization to custom needs, NdFeB magnets can be modeled in a variety of forms and dimensions, which increases their versatility,
  • Huge importance in advanced technology sectors – they are commonly used in mass storage devices, motor assemblies, medical devices, and other advanced devices.
  • Thanks to their power density, small magnets offer high operating force, with minimal size,

Disadvantages

Disadvantages of neodymium magnets:
  • At very strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (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 suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
  • We recommend a housing - magnetic mount, due to difficulties in producing threads inside the magnet and complicated forms.
  • Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these devices are able to disrupt the diagnostic process medical after entering the body.
  • With large orders the cost of neodymium magnets is a challenge,

Lifting parameters

Maximum lifting capacity of the magnetwhat it depends on?

The declared magnet strength refers to the peak performance, recorded under ideal test conditions, namely:
  • with the use of a yoke made of low-carbon steel, ensuring maximum field concentration
  • with a cross-section no less than 10 mm
  • with an ideally smooth touching surface
  • without any air gap between the magnet and steel
  • during pulling in a direction vertical to the plane
  • at room temperature

Determinants of practical lifting force of a magnet

During everyday use, the actual holding force results from a number of factors, ranked from crucial:
  • Clearance – existence of foreign body (rust, dirt, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
  • Angle of force application – maximum parameter is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
  • Steel thickness – insufficiently thick steel causes magnetic saturation, causing part of the power to be escaped into the air.
  • Material type – the best choice is pure iron steel. Cast iron may attract less.
  • Smoothness – ideal contact is possible only on smooth steel. Rough texture create air cushions, reducing force.
  • Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under shearing force the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet and the plate lowers the load capacity.

H&S for magnets
Adults only

Only for adults. Small elements can be swallowed, leading to intestinal necrosis. Store out of reach of kids and pets.

Threat to navigation

Remember: rare earth magnets produce a field that disrupts precision electronics. Keep a separation from your mobile, device, and navigation systems.

Data carriers

Data protection: Strong magnets can damage payment cards and sensitive devices (pacemakers, medical aids, mechanical watches).

Thermal limits

Keep cool. Neodymium magnets are sensitive to heat. If you need operation above 80°C, look for HT versions (H, SH, UH).

Powerful field

Handle with care. Rare earth magnets act from a distance and connect with massive power, often quicker than you can react.

Allergic reactions

It is widely known that the nickel plating (the usual finish) is a common allergen. If you have an allergy, avoid direct skin contact or opt for coated magnets.

Medical interference

Life threat: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.

Material brittleness

NdFeB magnets are ceramic materials, meaning they are prone to chipping. Collision of two magnets leads to them cracking into shards.

Finger safety

Protect your hands. Two powerful magnets will snap together instantly with a force of massive weight, crushing everything in their path. Be careful!

Dust explosion hazard

Combustion risk: Neodymium dust is explosive. Do not process magnets without safety gear as this risks ignition.
