　、リンｑ−ステルなどを１吏っている。As is well known, the magnetic fluid 40 is made by treating the surface of very fine ferromagnetic particles with an activator and uniformly dispersing them in a solvent to form a colloid. Magnetite and the like are generally used as magnetic particles. In addition, the solvents include water, Glossica-ster, Synthesis/14+

性質分持っていることが必要である。Currently, several types of magnetic fluids are used, but in the present invention, they are used in the following ways: 1) The solvent is insulating 1 2) High permeability 3 ) It is necessary to have properties such as not having a negative effect on the cable insulation.

It is Mi. Therefore, (the contact resistance between the layers IJ11 can be increased by the cardiac fluid. Also, since no eddy current flows through the single magnetic IA 40 between the wires 12, the thin current 4u is zero.

Note that since the internal full-gate tube 52 is closed, the magnetic fluid 40 containing a volatile solvent

In other words, the skin effect 1 series is, for example: 2! ;00mm split conductor, 79 for normal i1Q conductor without any treatment
