Abstract

A method for implementing a low-frequency rotating constant high magnetic field is disclosed. The method includes disposing an even number of more than two high field magnets, and disposing a magnetically permeable rotating arm. The high field magnets are symmetrically and fixedly mounted on the same surface of the magnetically permeable rotating arm. Magnetic poles of free surfaces of two symmetrical high field magnets are opposite. The area of the free surface of the high field magnet is larger than that of a connecting surface. A cross section of the high field magnet is in a geometric shape without edges or corners. A rotating apparatus drives the magnetically permeable rotating arm and the high field magnets to rotate.
