Green Square Magnetic Field Display Film Customized Size, Item No. MP-MVFILM03 series
The Magnetic Viewing Films allows you to “see” the magnetic field lines and in particular the field gradients at the interpole boundary as seen in the photo.
Magnetic viewing film (also called magnetic viewing paper) is made of millions of tiny magnetic flakes suspended in clear oil. This oil is then sandwiched between two sheets of plastic. The magnetic viewing film can then be used to “see” the pattern of magnetization. When a magnet is placed under the viewing film, the tiny metal flakes respond to the magnetic field, forming shapes similar to the pattern of magnetization. The white line(s) show the separation between the north and south poles of the magnet. Add a ruler to the equation and you can measure poles per inch.
While multiple poles spaced closely together can increase holding power, they can reduce the reach of the magnet. Inversely, when fewer poles are present, magnetic reach increases, but on contact, holding power is reduced.
Paper Magnetic Pole Detectors Description:
Easy to use. Just place the card on the surface of the magnetic material and it will reveal a magnetic field of pattern.
Great for personal or scientific research. And it help us study magnetic fields that we can’t see.
It can be used for quality control, product demonstration, reverse engineering, authentication and educational purposes. Magnetic Field Viewer Card
Compact and portable size, lightweight, convenient to carry with you.
Wonderful educational tool to stimulate our interest in science.
Magnetic field viewer is a micro-encapsulated film which makes user view a static magnetic field.
The highly flexible film suit for magnetic surfaces with any degree of convexity or concavity.
Size: About 50x50mm
