4 x 3 Inch Magnetic Field Viewing Film MV43

Product Description

The mv43 is a 4" x 3" green magnetic viewing film designed to reveal the magnetic field patterns of permanent magnets. The film appears darker where magnetic field lines pass perpendicular to its surface and lighter where the field lines run parallel to the surface, making it easy to visualize pole locations, magnetization patterns, and differences in magnetic field orientation. The mv43 is reusable and RoHS compliant.

The mv43 magnetic viewing film provides a simple way to visually examine magnetic fields without electronic equipment. Placed over a permanent magnet or magnetic assembly, it can reveal pole locations, magnetization patterns, and differences in magnetic field orientation that are difficult to see otherwise. It is a useful tool for engineers, educators, students, makers, hobbyists, and technicians working with magnets and magnetic assemblies. The mv43 can be used for identifying magnetic poles and patterns, comparing magnetization directions, inspecting magnetic arrays, troubleshooting assemblies, classroom demonstrations, STEM projects, and magnetic field experiments.
