发明名称 Apparatus for electromagnetically generating fields for repelling or attracting permanent magnetic fields for the purpose of entertainment
摘要 A device and method using an electromagnetic generator for generating magnetic fields to repel or attract permanent magnets which are placed in a specially configured mold comprised of a slotted non magnetic material attached to a base plate of non magnetic material. The permanent magnets are flat round disc shaped and are marked to identify polarity. The electromagnetic generator is placed beneath the mold and is energized through a momentary contact switch and a reversing selector switch for selecting the desired polarity. The electromagnetic generator is typically a coil powered by a suitable source of electric energy, typically rectified A.C. or D.C.. The reversing selector switch is employed to establish a fixed polarity while energized. A negative polarity of the electromagnetic generator will repel the negative polarity of a permanent magnet above it, ejecting it from its slot in the mold, causing it to move to another slot in the mold when properly directed by the position of the electromagnetic generator. A positive polarity will react to a positive polarity in the same manner.
