An experiment, measuring the changes of impedance in a magnetic wire, caused by the presence of a single domain wall was proposed. The results obtained from a magnetic wire with small helical anisotropy show that for lower frequencies (up to about 1 MHz), the presence of wall causes an increase in impedance, very probably due to the wall displacement. As frequency increases, the influence of the wall presence on the magnetic state causes the impedance to decrease in adjacent domains. For frequencies close to 10 MHz this effect overcomes the effect of wall displacement.
