(b) A simple experiment is conducted to investigate the effect of magnetic bar on the magnetic induction in the solenoid. A bar of cobalt, 99% pure material is placed in the coil as shown in Figure Q.2(b). A coil of wire is 0.20 m long and having 400 turns carries a current of 5 A. Cobalt has magnetic susceptibility of 249, a net magnetic moment per atom of 1.72 Bohr magnetons, an atomic weight of 58.93 g/mol, and density of 8.90 g/cm³. (i) Calculate the flux density (magnetic induction) with and without the cobalt bar in the coil. (ii) Compare your answer obtained in Q.2(b)(i). Does the cobalt bar affect the magnetic induction significantly? Why or why not? (iii) Compute the saturation magnetization, M, and the saturation flux density, B, for cobalt. Use Avogadro's number, N = 6.022×1021 atoms/mol and Bohr magneton magnitude. Ha =9.27x1024 A.m².
