Magnetic Field Viewing Film Manufacturer,Supplier and Exporter in Africa
Product Code : DA-M-11372
Quick Answer: The Magnetic Field Viewing Film is a flexible sheet coated with translucent microspheres containing tiny magnetic nickel flakes suspended in oil, which align along the field lines when a magnetic field is present.
Last updated: October 2026
Key Features
- Flexible sheet that shows the direction of magnetic field lines
- Translucent microspheres containing nickel flakes suspended in oil
- Flake alignment made visible by reflected light
- Laminated film: more durable and less easy to damage, suited to student use
- Non-laminated raw film: can be cut to any size or shape and wrapped around objects
- Shows complex pole geometry close to the poles; needs fairly strong fields
About This Product
Light reflected from the aligned flakes reveals the direction of the magnetic field across the sheet. One example is to wrap the film around a copper tube and watch the progress of a neodymium magnet as it slowly descends through the tube. The film is also used for quality control, product demonstration and reverse engineering, as well as in education. Export supply of the Magnetic Field Viewing Film can be arranged to laboratories and schools in Cyprus, Peru, Namibia, South Sudan and Laos.
Frequently Asked Questions
Q1. What is the difference between the laminated and non-laminated film?
The laminated film is more durable and less easy to damage, which suits student use. The non-laminated raw film is highly flexible and can be cut to any size or shape and wrapped around objects.
Q2. Does the Magnetic Field Viewing Film work with weak magnets?
It needs fairly strong magnetic fields, particularly when viewing complex pole geometry close to the magnetic poles.
Q3. How does the film show the field?
Nickel flakes in oil-filled microspheres align along the field lines, and reflected light from the flakes makes their alignment visible.
