A rectangular toroid with inner radius R1 = 7.0 cm, outer radius R2 = 9.0 cm , height h = 3.0 , and N = 3000 turns is filled with an iron core of magneticsusceptibility 5.2 × 103 . (a) What is the self-inductance of the toroid? (b) If the current through the toroid is 2.0 A, what is the magnetic field at the center of the core? (c) For this same 2.0-A current, what is the effective surface current formed by the aligned atomic current loops in the iron core?
