摘要： A method for manufacturing a spiral coil, the method including: forming a solenoid having a diameter larger than a length by spirally winding an insulated electric wire; forming a spiral coil having folded corners by folding four corners in a circumference direction with respect to the solenoid; fixing the folded corners of the spiral coil; and fixing two terminal portions corresponding to start and end points of the spiral coil to a fixing module. According to the method, a thin and long spiral coil having folded corners is easily manufactured by using a general insulated electric wire. In addition, the spiral coil manufactured by using such a method is applicable to a surface radio frequency (RF) coil optimized for various applications of an electro-magnetic acoustic transducer (EMAT) and enables easy access to an optimized transducer.
