A fascinating toy to learn and explore the behaviour of magnets and magnetic fields. Observe the effects of invisible magnetic fields using the sealed pattern window containing particles suspended in liquid that respond to a magnet. By placing the magnets either on top or underneath the window, the particles are attracted to and surround the magnet forming into clearly visible magnetic fields.
