    • A device for the manipulation of a biological material by a magnetic field is presented. The device comprises a magnetic field source coupled to a current source. The current source is of a kind supplying an electric current of at least two electrical degree shifted phases. The magnetic field source comprises a two-part inductor, each inductor part producing a coordinate varying magnetic field (CVMF). Each inductor part is formed by at least two conductors aligned in a spaced-apart relationship, wherein each of the at least two conductors is connectable to a different phase of the current source, and has two spaced-apart parts arranged such that when the conductor is connected to the current source, the electric current flows in its two parts in opposite directions, respectively. The conductors of each inductor part are arranged such that each two locally adjacent conductor parts are associated with two different phases of the electric current source. A distance between the two conductor parts coupled to the same phase of the current source defines a half-wavelength &lgr;/2 of a wave of magnetic induction of the CVMF. This distance is selected in accordance with a predetermined relation between the wavelength &lgr; and an effective space &Dgr; within the magnetic field region defined by the dimensions of the biological material and its distance from the magnetic field source.
    • 提出了一种用于通过磁场操纵生物材料的装置。 该装置包括耦合到电流源的磁场源。 电流源是提供至少两个电位移相位的电流的一种。 磁场源包括两部分电感器,每个电感器部分产生坐标变化磁场(CVMF)。 每个电感器部分由至少两个以间隔关系对准的导体形成,其中至少两个导体中的每一个可连接到电流源的不同相,并且具有两个间隔开的部分,使得当导体 连接到电流源,电流分别以相反的方向分成两部分。 每个电感器部分的导体被布置成使得每两个局部相邻的导体部分与电流源的两个不同相位相关联。 耦合到电流源的相同相位的两个导体部分之间的距离限定了CVMF的磁感应波的半波长lambd / 2。 该距离根据由生物材料的尺寸及其与磁场源的距离限定的磁场区域内的波长长度和有效空间DELTA之间的预定关系来选择。
