It looks like a 100 ohm resistor to me + or - 5 percent, I've scorched many, I could tell you for sure if you had taken your picture on the side of the resistor with the lesser damage. Take a few 100 ohm resisters, and smoke them, and compare the outcome.

Any eddy currents produced in the pipe would produce a counter magnetic field apposing the "changing" magnetic field of the rotating magnets. if the magnets have all the same poles, then the change in the magnetic field is mainly a change in field intensity, but if you have alternating field...
