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.

A MUSE is someone who is an inspiration to another person. Say there is an artist, they have regular periods of boredom and mind blanks, when they can't paint anything. Then there is a person, and for whatever reason, this person brings the artist much inspiration.
