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.

Internet art (often referred to as net art) is a form of digital artwork distributed via the Internet. This form of art has circumvented the traditional dominance of the gallery and museum system, delivering aesthetic experiences via the Internet.
