Abstract
A method and apparatus for processing substances electromagnetically having a container for receiving conductive working pieces and substances to be processed and magnetic field generators located adjacent said container to generate violent random motion of said working pieces is disclosed. The method comprises the steps of operating said apparatus at a first magnetic field intensity level slightly greater than the minimum intensity level required to generate random motion of said working pieces, and then periodically either increasing or decreasing the intensity level from said first intensity level to maintain random motion of said working pieces. Similarly, the apparatus comprises a timing mechanism which periodically either increases or decreases the intensity level from said first intensity level.
