Magnetic induction intensity is a crucial factor for determining the effect of electronic anti-fouling technology, while current is an important factor in determining the strength of magnetic induction intensity. The series resistance method is used in an electronic anti-fouling system in order to get the current value in the coil wrapped around the PVC pipe. The peak current in the circuit is obtained by measuring the voltage crossing series resistance, and the magnetic induction intensity in the midpoint of the solenoid coil is calculated by formula. Then a series of experiments are carried out to explore the change rule of current and magnetic induction intensity with respect to frequency, turns, and diameter. At the end of experiments, the results show that current in the coil decreases with the increase of frequency, number of turns, and pipe diameter. Magnetic induction intensity basically does not change with the increase of turns, and it decreases as the frequency and the diameter increase. Through the analysis of experimental data, the excellent processing parameter of the electronic anti-fouling technology is put forward, which provides guidance for the design and manufacture of the control unit.
