conductive pipe. The measurement is made with a coil. arrangement that produces a magnetic field that opposes the. primary field casing attenuation and phase-shift. The magnitude of the phase shift is a function of the casing electrical. conductivity, magnetic permeability and thickness of the metal present in the. field.
The long-tailed weasel is one of the larger members of the genus Mustela in North America, with a total length of 300â350 mm (12â14 in) and a tail comprising 40â70% of the head and body length.
