My magnetism

JEE Advanced Tutorials › Electricity and magnetism questions › My magnetism

Q charge is uniformly distributed over the same surface of a right circular cone of semi-vertical angle Î¸ and height h. The cone is uniformly rotated about a vertical axis passing through its vertex with Ï‰. Calculate the associated magnetic dipole moment.

use M = QL/2m where L=ang momentum, m=mass

So, M = Qw*I/2m where I=MOI of the cone abt the axis

and everyone knows MOI of cone about axis through axis is \frac {3 MR^2}{10}
