. A long solenoid with 10 turns / mm is to be used to magnetize two steel rods for MPI. One has a relative permeability of 20 and the other 75. If a flux density of 1.1 T is optimal for MPI, calculate the current that needs to be passed through the coil in each case. If the required magnetization is to be achieved by passing an axial current along the rod (diameter 10mm) calculate the current needed to produce appropriate field.
