Embodiment Construction
[0032] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:
[0033] The present invention proposes a method of utilizing the orthogonal alternating magnetic field and fragments moving in the magnetic field to form derotation torque. Its technical feature is that it contains the following contents:
[0034] (1) The action form of the magnetic field
[0035] In the plane perpendicular to the main axis of rotation of the non-magnetized metal fragments, two mutually perpendicular directions are arbitrarily selected, with the passing point of the main axis of the fragments as the origin, and the two perpendicular directions are respectively marked as x-axis and y-axis. A magnetic field N and a magnetic field M are applied in two axial directions, respectively. For the convenience of discussion, it is stipulated that when the rotation direction of the debris is counterclockwise, it is positive, the positive direction of the mag...
