Mysterious spinning top
Give this spinning top a spin and watch it spin for hours without stopping.
The secret revealed: the spinning top contains a small magnet. As this magnet moves past the center of the black base, the top’s magnetic field induces a current in a coil, which closes a switch, allowing a battery to instantly activate a small electromagnet. The spinning top increases its speed and spins away from the center of the base.SKU: FR-313110 -

Neodymium magnets Ø12 mm
The neodymium magnets have a diameter of 12 mm, a height of 4 mm and a weight of 3.4 g. They are of the N45 type, which means that they are very powerful in relation to their size. The magnets are made of neodymium, which is known for its high strength and stability, and they can therefore hold a considerable weight despite their compact shape.
