1. The Effect of Magnetic Fields on Combustion and Gas FlowWe have observed that combustion and gas flow in the air are influenced by magnetic field gradient in the range of 50-100T/m under 1-2T. We have introduced a model of a "magnetic curtain" to explain these phenomena. It is assumed that the magnetic curtain is an "air curtain" which is formed by magnetic fields. We simulated the gas flow near magnetic curtain, introducing a technique of molecular dynamics. We applied this phenomenon to magnetic separation of fine particle dust in the air and to the control of heat transport in heat pipes.2. Nerve Stimulation by Pulsed Magnetic FieldsWe proposed a new method of localized nerve stimulation by a pair of opposing pulsed magnetic fields. Magnetic stimulation of the human motor cortex was realized with a 5 mm resolution. The basic idea is to concentrate induced eddy currents locally in the vicinity of a target by a pair of opposing pulsed magnetic fields. Using this method, the functional mapping of the motor cortex was obtained. We also observed that the functional mapping of the motor cortex was changed with the direction of induced eddy current flow.3. Biological Effects of Intense Magnetic FieldsThe possible influence of intense magnetic fields up to 6.34T on the early embryonic development of Xenopus laevis was studied. The magnetic fields up to 6.34T did not affect appreciably the rapid cleavage and the following cell multiplication and differentiation in Xenopus laevis.
