Hello, I wasn't really sure as to where to post this, since it kinda doesn't really fit in with the listed categories, but I have a question. I work at a chem lab that specializes in Non-Destructive testing, and I am also minoring in Non-Destructive testing in college. In the engineering department, a long metal pipe was magnetized using a large magnetic coil of 120 turns, and it never overlaps itself. Only, the pipe did not develop a negative end and positive end like a magnet. The charges on the pipe are as shown in the attachment picture. I was asked why this is. The only things I could come up with were that it could be the material of the pipe, the length of the pipe, a flaw in the pipe, or the amount of voltage/amps used were too low to magnetize the pipe. The coil used 80 volts, twice that of what the company says is a safe level of voltage to use. No one can seem to figure this out, so hopefully some of you nice smart people can help me determine why this is, or if I am just having a stupid moment, and overlooking something obvious. Anything is appreciated. Thanks!
