Practical Design

  • Versatility: can be used on various surfaces such as refrigerators, ceilings, vans, workplaces and tool storage
  • Strong magnetic pull force: holds up to 22kg in horizontal position
  • Swivel hook design: allows for easy adjustment of hanging angle
  • Black hook: adds a touch of style to your space
  • Easy to install: no drilling or tools required

Our magnet hooks are made of high-grade Nd-Fe-B materials. Neodymium magnets are the strongest type of permanent magnet currently made. They are amazingly powerful for their size and have innumerable uses.

Several Important Factors Affecting the Tensile Force of Magnets

  • Only when the thickness of the tested steel reaches a certain level, the magnetic flux through its cross section would be the largest and the leakage magnetic field between the magnetic poles is the smallest, the tensile energy can reach the ideal value.
  • Only when the force is perpendicular to the contact surface can the tension reach the maximum. When the force is parallel to the contact surface, the pulling force can only reach 1/3 maximum.
  • Magnets attract only magnetizable materials such as iron, cobalt, nickel and their alloys. It can not attract non-ferromagnetic plates such as aluminium, copper, wood, plastics and stainless steel.
  • The farther the magnet is from the magnetic material, the greater the leakage magnetic field and the smaller the pull force would be. Therefore, the surface paint adsorption by magnets is also an important factor affecting the pulling force of magnets.

WARNING

  • Keep away from pacemakers.
  • Powerful magnets can hurt your fingers.
  • Strong magnet - Not for children, parental supervision is required.
  • All magnets may chip and shatter, but if used correctly, can last a lifetime.
  • The maximum working temperature of neodymium iron boron magnetic is 80 C

Demagnetization Curves
Surface Treatment

The most common coating for Neodymium magnets is Nickel + Copper + Nickel (Ni + Cu + Ni). This coating offers the magnet relatively good protection from corrosion and passive applications. If the magnet will be exposed to moisture or liquid then consider the use of an organic coating such as Epoxy. A hard wearing coating, Epoxy is suited to applications where the magnet will come under some friction or knocking.

Range and Tolerance

Magnets are readily available in Blocks, Discs, Cylinders & Rings. AMF Magnetics specializes in the supply of short-run prototype magnets including Arc Segments, various magnetic orientations etc. If you need a magnet size that we don't carry in stock, submit a Design-a-Magnet enquiry for a quote on your custom magnet design.

Magnetic Properties

Neodymium magnets are offered in several different grades. The first section N30-54 has an operating temperature of up to 80 degrees. Most of our stock only goes up to N38. The second section, denoted with the "M" prefix after the grade has an operating temperature 100 degrees. After this the grades are "H", "SH", "UH" & "EH". In order for the magnet to withstand a higher operating temperature, during production more of the raw material PrNd is incorporated as these elements have a naturally occurring resistance to high temperatures.
