As Figure 32.4 (page 318) indicates, there is a region of more or less uniform magnetic field inside a solenoid when it carries an electric current. The flux density can be varied by filling the solenoid with a core of material. So-called diamagnetic materials slightly reduce the flux density and paramagnetic materials slightly increase it. On the other hand, ferromagnetic materials increase it greatly, some by a factor of many thousands.
