An electron with kinetic energy Ke travels in acircular path that is perpendicular to a uniform magnetic field,which is in the positive direction of the z-axis. The electronsmotion is subject only to the force due to the field. (a) show thatthe magnetic dipole moment of the electron due to it's orbitalmotion has magnitude μ0=Ke/B and that it isin the direction opposite that of B. What are the (b) magnitude and(c) direction of the magnetic dipole moment of the positive ionwith kinetic energy Ki under the same circumstances?(d)An ionized gas consists of 5.3*10^21 electrons/m3 andthe same number density of ions. Take the average kinetic energy tobe 6.2*10^-20 J and the average ion kinetic energy to be 7.6*10^-21J. Calculate the magnetization of the gas when it is in a magneticfield of 1.2 T.
