Sensitive magneto-inductive effect in amorphous wires using high-pass filter and micro field sensor

A highly sensitive magneto-inductive effect was found in amorphous wires using a high-pass filter observing the variation of the frequency spectrum of an induced voltage waveform between both ends of the wire before and after applying an external field. A sensitive micro sized magnetic field sensor was constructed using a pair of the magneto-inductive elements of 3 mm length applying dc bias fields opposite to each other.<
