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.

What is a conservator? Conservators are professionals who work to physically save our cultural property from the ravages of time, the threats of pollution, and the devastation brought by natural disasters. A conservator may be trained at a conservation graduate training program or by lengthy apprenticeship with experienced senior colleagues. Working in museums, other cultural institutions, research labs, and in private practice, conservators combine unique skills gained through ongoing study and advanced training in art history, science, studio art, and related disciplines to care for and preserve our tangible history.
