Asolid sphere of radius a has auniform magnatization

in the zhat direction. what is the magnetic dipolemoment of the
sphere?

Answers and Explanation:

The step by step explanation is clearly screenshot in the two attachments below for easy understanding.

NOTE:

A uniform charged solid sphere of radius R carries a total charge Q, it therefore has its charge density as Q/(4/3ΠR³). And to find magnetic moment of a sphere, the sphere has to be divided into infinitesimal charges.

Magnetic Dipole Moment of the sphere would be given as 1/5QwR²z

f=ma newton

f=100x2.5=250n

answer is slate

hope this
