How Magnetic Viewing Film Acts as a Magnetic Field Visualizer

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.

How Do You View a Magnetic Field?

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. Read about methods of magnetization and the sizes of magnetic viewing paper we offer.
