A 1 mm thick, cylindrical iron pipe with inner diameter of 1 cm and outer diameter of 1.2 cm
surrounds a long, 4 mm diameter copper wire carrying a current of 10 A (into page, uniform
throughout cross section of wire). Assume that iron is a linear isotropic magnetic material with
relative permeability, r= 100. There is no electric current in the pipe. Copper has a relative
permeability of 0.999994 (pretty darn close to 1).
On the axes below, plot the magnitudes of B, H and M as a function of r, the distance from the center of the wire. (Include points
outside of the pipe.)
On the vertical axes, indicate the maximum value that each of the quantities reaches. Be sure to include the correct units.
