Magnetic systems generating HGMF. Bold arrows indicate the direction of force acting on diamagnetic substances. A, HGMF at the edge of a gap between two magnets or magnetic poles repels diamagnetics from the gap. The dispersion of the magnetic field at the edge of the gap between two magnets results in a decrease of field intensity. The field in the depth of the gap reached 8 kOe, the dynamic factor ▿(H2/2) at the edge of the gap was estimated to be 5.3 × 108 Oe2 cm−1 (Kuznetsov and Hasenstein, 1996). B, Position and the predicted curvature of wwr protonemata near the edge of the gap between two magnets. C, The field in the vicinity of a ferromagnetic wedge between two magnets concentrates the field near its protruding edge such that LH is directed toward the edge. Therefore, diamagnetic plastids experience a force that is directed away from the wedge. L(H2/2) in close proximity of the edge can exceed 1010 Oe2 cm−1. D, Relative position of the magnetized wedge and protonemata with the projected curvature of the WT. E, Gradient of the field around a spherical magnet is directed toward the particle, hence diamagnetic particles will be repelled from it. Near a small (<1 mm) but strong magnet, the dynamic factor of the field L(H2/2) can exceed 109 Oe2 cm−1.
