in this paper. The results show that the diameter of drive coil is an important
factor affecting the giant magneto-impedance effect of Fe-based alloy strips.
The smaller the diameter of drive coil is, the more obvious the giant
magneto-impedance effect is. And the maximum impedance ratio (Δ</span><span style=\"font-size:14px;\">Z</span><span style=\"font-size:14px;\">/</span><span style=\"font-size:14px;\">Z</span><span style=\"font-size:14px;\">)</span><span style=\"font-size:14px;\"><sub>max</sub> </span><span style=\"font-size:14px;\">of the magnetic core drive coil decreases
exponentially with the increase of the diameter of the magnetic core
