WebQuestion: 4) Consider a system of N non-interacting particles, each fixed in position, and carrying a magnetic moment μ, which is immersed in magnetic field B (a paramagnet). Each particle may exist in one or two energy states: E =-B and E-t㎕. Treat the particles as indistinguishable. WebA magnetic pole is the part of a magnet that exerts the strongest force on other magnets or magnetic material, such as iron. For example, the poles of the bar magnet shown in Figure 20.2 are where the paper clips are concentrated.

"WebThe classical answer is simple: A magnetic moment m is generated whenever a current flows in closed circle. Of course, we will not mix up the letter m used for magnetic moments with the m*e , the mass of an electron, which we also need in some magnetic equations. For a current I flowing in a circle enclosing an area A, m is defined to be m = I · A " - Fixed_magnetic_moment
