Magnetic Field Viewer Film

Magnetic Field Viewer Film, High Resolutions Magnetic Field Viewing Film, Thin Green Magnetic Viewing Film, Magnetic Field Viewer Paper, Magnetic Field Display Film, High Definition Square Magnet Viewing Film supplier exporter

This High resolutions magnetic field viewer film allows you to identify the magnetic field patterns of magnetic materials and assemblies. The viewing film can be used to check for damage to the magnet material within most types of magnet assemblies. Simply hold the film against the surface of any magnet and the pattern of the magnetic field is revealed. The sheets are reusable. Simply place the film directly on the surface of the magnetic material in question and instantly reveal a magnetic field of any shape or pattern. You can easily identify the poles. The film is highly flexible and quite durable. It can be laminated. Available as 12 in. x 12 in., 24 in. x 24 in., 3 in. x 3 in.,6 in. x 6 in., or a 36 in. x 36 in. strip perfect for use with our Eddy Current Tubes.

These magnetic field viewers are sometimes referred to as magnetic field detectors, magnetic field paper or magnetic field film. Viewing a magnetic field is quick and easy with this Magnetic Field Viewer brought to you by HSMAG.

The Magnetic Field Viewer is a translucent paper-like substance which makes magnetic fields visible. The thin green film is filled with millions of iron particles suspended in oil. This allows enough freedom for the particles to align with an externally applied magnetic field – thereby displacing the coloured fluid and causing a colour change at the surface of the film. A magnet will attract the particles to the areas where the magnet is the strongest, at its poles. When held near a magnet, the viewer appears dark green in regions where the field is perpendicular to the card and light green where the field is parallel to the card.
These viewers have been used in classrooms to explore the magnetic field near a variety of magnets as well as near wire loops. The effect is interesting when you have lots of magnets orientated in different directions.

Features of Magnetic Field Viewer:
Laminated to protect the fragile paper and provide long term use.
A great resource to help education adults and children about the concepts of magnets and magnetic poles.
Safe to use.
Easy and fun to use.
