电子变压器的磁性基本现象分析!（Analysis of the magnetic basic phenomenon of electronic transformer!） Analysis of the magnetic basic phenomena of electronic transformer The magnetic basic phenomenon of electronic transformer Electrons always flow along the path of least resistance in a conductor. On the surface of the conductor and the surface of the surface, the structure element is basically parallel to the surface of the conductor, and the transfer resistance of the electron is small. And on the internal structure of conductor yuan are arranged from top to bottom, left and right sides, front and back space, electronic directional flow in to resistance by the five directions, (and only three directions in surface resistance) visible electronic run near the conductor surface resistance than within a much smaller, thus lead to the current skin effect. Second, when electrons to move within the conductor in the vertical direction of movement associated with magnetic field, (right-hand rule) under the action of other electronic in magnetic field to spread gradually to the surrounding mobile, then move to near the surface of the wire, formed the current skin effect. Third, of course, the influence of the temperature: inside the conductor, resistance of heat to send out, the temperature is higher, the price and electronic operation rate is high, the line is not very flat, thus lead to the electronic circuits is relatively narrow, resistance is high. On the surface of a conductor, quick cooling, low temperature, low price and the rate of electronic operation, circuit flat, thus lead to the electronic access relatively broad, and so the conductor surface resistance is small, the foreign electronic run faster, this is also one of the reasons for the current skin. Point discharge when a part of conductor do very fine is very sharp, pointed part of the surface area is opposite bigger, transposition to move to the electron density is relatively larger, and even a little crowded in cutting-edg
