Abstract :
A magnetic inductance tomography system has been developed in this paper. The variations of the magnetic field due to the object are designed to be measured by Hall sensors located around the tube. The sensing signals are computed by nonlinear finite-element analysis. The computed signals according to the size and location of the object agree well with experimental measurements.
