LEP 4.4.03 Inductance of solenoids
... As a difference in length also means a difference in the number of turns, the relationship between inductance and number of turns found in Problem 1 must also be used to solve Problem 2. Notes The distance between L1 and L should be as large as possible so that the effect of the excitation coil on t ...

... If a piece of iron is inserted in the solenoid, the magnetic field greatly increases, because the iron becomes a magnet. The resulting magnetic field is the sum of the field due to the current and the field due to the iron, and can be hundreds or thousands time of the field due to the current alone. ...
