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.

Connoisseurs evaluate works of art on the basis of their experience of the style and technique of artists. Judgment informed by intuition is essential, but it must be grounded in a thorough understanding of the work itself.
