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.
The Common Weasel (also known as the European Weasel and the Least Weasel) is the most wide-spread and can be found across much of the northern hemisphere. These tiny but vicious predators are the smallest carnivorous mammals in the world growing to no more than 6 inches from their nose to the tip of their tail.he Weasel is a solitary animal that spends a great deal of it's life hunting for small mammals on the ground during both the day and night.
