the turn density is n=N/L = turns/m. If the current in the solenoid is I = amperes. and the relative permeability of the core is k = , then the magnetic field at the center of the solenoid is. B = Tesla = gauss. The Earth's magnetic field is about half a gauss.The relative permeability of magnetic iron is around 200.n the above expression for the magnetic field B, n is the number of turns per unit length, sometimes called the turns density.
