A rod is inserted as the core in the current-carrying solenoid of the previous problem. (a) What is the magnetic intensity `H` at the centre? (b) If the magnetization `I` of the core is found to be `0.12 A m^(-1)`, find the susceptibility of the material of the rod. (c) Is the material paramagnetic, diamagnetic or ferromagnetic?
