Patent ID: 8827885

Claim:
A method for implementing a low-frequency rotating constant high magnetic field, comprising: disposing at least one pair of high field magnets including a first high field magnet and a second high field magnet, and disposing a magnetically permeable rotating arm, wherein the first and second high field magnets are symmetrically mounted relative to a rotation axis, the first high field magnet having a first connecting surface, and the second high field magnet having a second connecting surface, both of the first and second connecting surfaces are fixedly mounted on a same surface of the magnetically permeable rotating arm, wherein the first high field magnet has a first free surface generally opposite to the first connecting surface, and the second high field magnet has a second free surface generally opposite to the second connecting surface, a magnetic pole of the first free surface is opposite to a magnetic pole of the second free surface, wherein an area of the first free surface is larger than an area of the first connecting surface, and an area of the second free surface is larger than an area of the second connecting surface, wherein a cross section of the first high field magnet is in a geometric shape without corners, and a cross section of the second high field magnet is in a geometric shape without corners, wherein a rotating apparatus drives the magnetically permeable rotating arm and the first and second high field magnets to rotate about the rotation axis, and wherein an area of a cross section of the first high field magnet decreases from the first free surface to the first connecting surface, and an area of a cross section of the second high field magnet decreases from the second free surface to the second connecting surface.
