The kit consists of a non-magnetic support on which slides down two ring magnets, so arranged that the magnetic poles of same sign be face to face. Between the two magnets (the magnetic field sources) there is an interaction of magnetic fields, proportional to the distance between them. It also appears gravitational attraction and influence.

Technical specifications:

• Outside diameter of the magnet: 60mm
• Inside diameter of the magnet: 25mm
• Thickness of the magnets: 8-10mm
• Bd (induction of dispersion): 1200-1800 Gauss
• South pole marked with blue paint
• North Pole marked with red paint
