The magnetic moment ( m _ orb ) of a revolving electron around the nucleus varies with the principal quantum number (n) as

Step-by-step solution

Orbital magnetic moment can be defined as, m _ orb = iA where, i = e T , r is the radius of the Bohr orbit, A = r ^2 is the area and T is the time period of uniform circular motion. Now, we can make use of the Bohr's hypothesis about angular momentum: On plugging in above into equation (1), m _ orb = neh 4 m Orbital magnetic moments of an electron in Bohr orbit is given by, aligned & m _ orb = n ( eh 4 m ) & m _ orb n aligned
