The driving coil is optimized by replacing the magnetic field with ampere turns. For a variety of wire diameter, select the appropriate trade-off between the ampere-number maximization and the power minimization when the volume is closest to its allowable value and does not exceed the maximum output current of the power supply. It is calculated that 1mm diameter coil has the minimum power consumption. Therefore, choose 1mm diameter enameled wire to wound coil.
