PURPOSE:To provide a magnetic spring, which comprises a cylindrical magnet with its inner and outer sides differently polarized, and a magnetic rod having its opposite ends differently polartzed, the magnetic rod being inserted into the cylindrical magnet thereby their positional relation under no loae being stabilized. CONSTITUTION:A cylindrical magnet 1 is magnetized in such a way that the inner side thereof has a N pole and the outer side thereof has a S pole. An upper end of a magnetic rod 2 has a N pole and a lower end thereof has a S pole, and it is inserted into the cylindrical magnet 1. The magnetic rod 2 will be floated and will not get out of place at a certain point where the force of the cylindrical magnet 1 which atracts it will be balanced with the repelling force between the magnet 1 and magnetic rod 2 and the weight of the magnetic rod 2, so that the positional relationship between the cylindrical magnet 1 and the magnetic rod 2 under no load will be stablized. |
