• Description:
  This is another great device to help you see magnetic fields. It is a thin film containing powdered iron and a green oil. Place the film onto a magnet and see where the poles are located and the line between the poles. You can easily see the strips of N and S poles on the back of inexpensive refrigerator magnets! The way it works, is that either a North pole or a South pole will appear very dark green, almost black. The line which divides the North from the South poles appears very light green, almost white. This way, you can see how many N and S dividing lines there are
