The induction of the magnetization may be measured by observing the force required to draw apart the two portions of a divided rod or ring when held together by their mutual attraction.
Many of the physical properties of a metal are affected by magnetization.
If the direction of the magnetization at the surface of a magnet makes 3 The C.G.S.
A thin sheet of magnetic matter magnetized normally to its surface in such a manner that the magnetization at any place is inversely proportional to the thickness h of the sheet at that place is called a magnetic shell; the constant product hI is the strength of the shell and is generally denoted by 4, or 4.
The magnetic susceptibility expresses the numerical relation of the magnetization to the magnetizing force.
