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.

SmCo Magnets

Samarium Cobalt MAGNETS

Permanent Samarium Cobalt magnets (SmCo) are composed of samarium, cobalt and iron.
These rare earth magnets are extremely strong for their small size, metallic
in appearance and found in simple shapes such as rings, blocks and discs.

Attributes of Samarium Cobalt

  • High resistance to demagnetization
  • High energy (magnetic strength is strong for its size)
  • Good temperature stability
  • Expensive material (cobalt is market price sensitive)

Applications of Samarium Cobalt

Computer disc drives, sensors, traveling wave tubes, linear actuators,
satellite systems, motors where temporary stability is vital.

Magnetizing and Handling

Samarium Cobalt magnets are very brittle and very strong magnetically. Therefore,
it is crucial to handle these magnets with extreme care to avoid personal
injury and damage to the magnets. Fingers can be severely pinched between
attracting magnets. Magnets can chip if allowed to “jump at” an
attracting object. It is highly recommended that when constructing rare
earth magnetic assemblies, they be magnetized after assembly.

Samarium Cobalt Machining

Since Samarium Cobalt magnet material is prone to chipping and cracking,
it does not lend itself to conventional machining methods. It can, however,
be abrasively ground, but only with the use of liberal amounts of coolant.
The coolant minimizes heat fracturing and the risk of fires caused by
oxidized grinding dust.

Micro SmCo Magnets

Micro magnets

We specialise also in thin-walled and slot-opening miniature ring magnet through laser incising, drilling and processing SmCo material. Serial products of SmCo ring magnets, precious stone bearings, etc. are widely applied in fields of miniature motor, optical communication, instrument and meter, watch, electro acoustic, etc. The products are exported to the countries and areas of Switzerland, Germany, Hong Kong, etc. and win favor at home and broad.
