Viewing a magnetic field is quick and easy with this credit card-sized laminated viewing film enclosing a suspension of minute iron particles in oil.
The small particle size defines the shape of the magnetic field more precisely than filings and reveals the poles of weak magnets as well. Viewing film is 2"x1.5" in size.
