  • Title: [A project of magnetic coils newly designed to restrain the negative value of the intensity of magnetic induced electric field].
    Author: Liu Z, Yin T, Guan X.
    Journal: Sheng Wu Yi Xue Gong Cheng Xue Za Zhi; 2003 Mar; 20(1):45-8, 59. PubMed ID: 12744160.
    Abstract:
    In the non-invasive magnetic nerve stimulation of human brain, the coil of figure "8" is mostly used. The peak maximum is corresponding to the center of the coil, and the negative peak value is corresponding to the twain edges of the coil, the latter one is apt to cause abnormal nerve excitation. In this text, we put emphasis on the study of abnormal stimulation induced in magnetic stimulation and analyse the electric field intensity of the figure-8 coil. Aiming at the large negative value of intensity, we develop a new structure coil to restrain abnormal stimulation. Theoretical simulation is demonstrated here also.
