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. In most populations, females are 10â15% smaller than males, thus making them about the same size as large male stoats.
Weasel. Weasels are adaptable little mammals that live almost anywhere they can find cover and prey. This includes sand dunes, grassland, woodland and mountains. They must eat every 24 hours to avoid starvation, so are active both day and night, alternating periods of activity with a few hours of rest. Weasels eat rodents, such as voles and mice for the most part, supplemented by birds or eggs when available.
