Answer:
Magnetic dipole moment is 0.0683 J/T.
Explanation:
It is given that,
Length of the rod, l = 7.3 cm = 0.073 m
Diameter of the cylinder, d = 1.5 cm = 0.015 m
Magnetization, 
The dipole moment per unit volume is called the magnetization of a magnet. Mathematically, it is given by :


Where
r is the radius of rod, r = 0.0075 m


So, its magnetic dipole moment is 0.0683 J/T. Hence, this is the required solution.
