Square coil now has a new discovery: the effective compensation for the distortion of the square coil of the characteristics, the display is we all require the picture is square, the electron beam through the coil to obtain the magnetic field, and the magnetic field generated by a square coil is the characteristic of this.
Now online circle circle of friends slowly will note that the use of the coil can improve efficiency, now it is the best description of the square coil, and the use of square coil, now the RTC deflection coil in the same condition of the power savings of a lot, it is more and more popular, why do so, before the square coil is not strong, and now it is not the same. The field of application has been explained by this point.
