A research on electromagnetic induction of electromagnetic tomography object field

This paper investigates the electromagnetic induction question of detected object in object field aiming at electromagnetic tomography. The object field takes parallel field as exciting mode and the sensor part is composed of 16 excitation plates and 8 detection plates. When it works, electric current applied all the excitation plate at the same time with amplitude showed sinusoidal distribution in circle. The system is simulated by Ansoft software. By a change of the exciting frequency of the time-varying field, material characteristics, as well as the location and the size of the objects and other factors to study the electromagnetic induction phenomenon of the electromagnetic tomography in object field.
