The Flux Detector Large consists of a film filled with nickel particles in a gelatinous suspension. It allows magnetic fields to become visible. The flux detector turns dark in colour when the magnetic field is perpendicular to the film (for example, near the poles) and turns lighter when the magnetic field runs parallel to the film.

It is the same article as the Flux Detector Small but with 4 times the surface area. Other sizes are available upon request.

Where are the poles of this magnet cube W-12-N? Since the Flux Detector turns dark wherever there is a magnetic field, the poles must be, in this case, on the top and bottom sides of the cube.
In this photo the magnetic poles are on the left and right side of the cube. In the middle between the two poles there is no magnetic field - the Flux detector shows this as a light line.
30 magnetic spheres K-08-C are behind this Flux detector. The light stripes display the change from a north to a south pole. Such changes in polarity abound at the contact points between the spheres as well as in the centre of every sphere. 60 of these light stripes can be seen in this photo.
Behind this Flux detector is the giant magnet Q-25-25-13-N, whose contour is easy to see. Its poles are on the left and right side. The light strips show the area between the poles where there is no magnetic field. The darker areas show the location and intensity of the magnetic field very well.
The detector maintains the last pattern until a new magnetic field is shown. Therefore, the flux detector won't be all green anymore once you started using it, but you'll see dark shadows.
