Abstract
A purification apparatus includes a first flow path for introducing and discharging water and magnetic field generation means provided on a way of in the flow path for giving a magnetic field in the flow path. The introduced water includes magnetic substances. In the flow path in which the magnetic field generation means is disposed and in the magnetic field generated by the magnetic field generation means, a second flow path is provided in such a manner that the second flow path is guided toward the outside from a region in which a magnetic gradient is decreased. Further, there are provided means for moving the magnetic substances in the vicinity of the second flow path, magnetic substance sensing means provided in the flow path, and control means for controlling in response to a signal from the sensing means an amount of the magnetic substances which flow through the second flow path.
