Magnetic Field Viewer Film

Magnetic Field Viewer Film

Magnetic Field viewer is a micro-encapsulated film which enables the user to view a static magnetic field such as commonly emitted by permanent magnets or dc electromagnets. Simply placing the film directly on the surface of the magnetic material in question can instantly reveal a magnetic field of any shape or pattern.
Get Magnetic Field viewer Film in stock from SupraMagnets.com online.
The highly flexible film easily conforms to magnetic surfaces with any degree of convexity or concavity. Magnetic Field viewer is used across the globe for quality control, product demonstration, reverse engineering, authentication and educational purposes.
Encased within the green film are millions of magnetic particles suspended in oil. A magnet will attract the particles to the areas where the magnet is the strongest – at its poles. The poles appear dark green. Multiple pole magnets such as those on business card magnets will display interesting patterns, such as the example pictured below.

The film is highly flexible and can wrapped arround objects.
The viewer film come from the factory as a uniform green. However, once the film is exposed to a magnetic field, black lines or dark areas will remain in the film, even after the magnetic field is removed. This is normal behavior for the film. The film can be re-used over and over again and will continue to show the magnetic field of sources strong enough to coerce the the suspended iron particles in the film.

There is no practical way to reset the film to the uniform green from the time of manufacture. Exposing the film to a very large magnet or magnetic field can bring the film fairly close to an even color. Customers have reported that magnetic tape de-gaussers, used to erase audio tape, work fairly well at restoring the original green color to the film.

Cast AlNiCo Magnets

Cast AlNiCo Magnets

AlNiCo material is comprised of aluminum,nickel,cobalt and iron with varying additions of other elements.There are two different manufacturing processes for AlNiCo:Cast and sintered.

Alnico magnets can be made into many shapes and sizes during manufacturing process by using the casting processing method. Cast Alnico magnets are manufactured by pouring the molten metal alloy of Alnico into a mold and then further processing it through heat treated and cooled alternatively. The solidified material has a dark gray appearance on the exterior and may be roughly ground. Magnets that have been polished using machines, may have a shiny gray surface similar to that of steel.

Attributes of Alnico Magnets:

  • high flux density
  • superior temperature stability
  • economical and suitable for the manufacture of magnet of relatively large size
  • excellent temperature characteristics of any standard production magnet material available

Applications of Alnico Magnets:

  • precision instruments
  • advanced electrical meters
  • water meters
  • mobile odometers
  • eletricity motor switch
  • sensors
  • electroacooustic and telecommunication devices
  • spinning topes and microwave devices

Sintered AlNiCo Magnets

Sintered AlNiCo Magnets

AlNiCo material is comprised of aluminum,nickel,cobalt and iron with varying additions of other elements.There are two different manufacturing processes for AlNiCo:Cast and sintered.Cast AlNiCo can be made into many sizes and shapes,whereas Sintered AlNiCo is usually restricted to smaller sizes.However,both processes lead themselves to complex geometries and configurations.Standard Sintered AlNiCo has tighter dimensional tolerances due to its processing.It also has slighty lower magnetic properties,but better mechanical strength than Cast AlNiCo products.They are most suitable for small sizes that are less than 1 oz. It also results in parts that are structurally stronger than the cast alnico magnets. With the sintering process, one can achieve relatively close tolerances without any grinding.

Sintered Alnico magnets are formed by compacting fine Alnico powder in a press and then sintering the compacted powder into a solid magnet. The powdered mixture of contents is pressed into a die under tons of pressure. It is then sintered in a hydrogen atmosphere at 2300F and then cooled – either within a magnetic field or without a magnetic field. When cooled within the magnetic field it is known as an anisotropic magnet and when cooled outside of a magnetic field it is called an isotropic magnet. The sintering process is well suited to large volume production.

Attributes of Alnico Magnets:

  • High mechanical strength, suitable for small volume magnets with complex shape.
  • Working temperature can reach 550-600 °C
  • Does not lend itself to conventional machining (hard and brittle)
  • Good corrosion resistance;
  • High residual induction and energy product compared to ceramic material
  • Excellent temperature stability (temp. coefficient of Br is the smallest among all of the other permanent magnets)

Applications of Alnico Magnets:

  • Relays
  • Controls
  • Generators
  • Receivers
  • Telephones
  • Bell ringers
  • Loudspeakers
  • Cow magnets
  • Microphones
