Unformatted text preview: = K e /B . Thus, the relation = K i /B holds for a positive ion. If the magnetic Feld is directed into the page, the ion travels counterclockwise around a circular orbit and the current is in the same direction. Therefore, the dipole moment is again out of the page, opposite to the magnetic Feld. (c) The magnetization is given by M = e n e + i n i , where e is the dipole moment of an electron, n e is the electron concentration, i is the dipole moment of an ion, and n i is the ion concentration. Since n e = n i , we may write n for both concentrations. We substitute e = K e /B and i = K i /B to obtain M = n B ( K e + K i ) = 5 . 3 10 21 m 3 1 . 2 T ( 6 . 2 10 20 J + 7 . 6 10 21 J ) = 310 A / m ....
