This item is a transparent frame containing magnetic particles in a water-based solution for showing magnetic field patterns. When a magnet is present, the particles of iron inside become slightly magnetized, so they attract each other and cluster into the lines that show the magnetic field patterns. The kit offers an interesting visual method of showing the power of magnetic fields.
