“…The annular coil is symmetrical, so the value of the positive and the value of the negative current are close to the size. The maximum Bx of positive current direction is 5 2.4782 10   T, and the maximum Bx of negative current direction is 5 2.4053 10   T. It can be seen from the figure 1(c) and 1(d) that the magnetic flux density By in the direction of coil plane along the y axis is similar to Bx. The maximum of magnetic flux density By in the positive direction and negative direction are respectively 5 2.0527 10   T and 5 2.3703 10   …”

“…The magnetic flux density is larger near the inner on the edge of the coil, and it appears negative value near the outer of the coil. The positive maximum for magnetic flux density Bz is 5 5.6303 10   T, and the negative maximum for Bz is 5 7.5107 10   T. The non-zero magnetic flux density in the z axis direction appears in the middle of the coil, especially in the center. According to Faraday'law, the magnetic flux density is through from the middle of the coil.…”

Magnetic induction tomography is a new reconstruction image technology with advantage of non-invasive, nondestructive. The low conductivity for human leads to the weak eddy current field which reflects human conductivity distribution. After analyzing the traditional annular excitation coil without focusing effect, the lid shape spiral coil is proposed which can produce focusing magnetic field. The measurement model with the target object is established for the focusing excitation coil. The primary field and the eddy current field produced within the target object are calculated and analyzed comparatively. The results show that the proposed focusing excitation coil can produce the focusing primary field and focusing eddy current field in the target object, providing an effective method for MIT from the eddy current source.
