SUMMARY
The magnetic moment associated with a charge q rotating in a circular orbit of radius r and angular velocity ω is calculated using the formula μ = (qωr²)/2. The current I generated by the orbiting charge is derived from the relationship I = q/T, where T is the period of rotation, given by T = 2π/ω. This establishes a direct connection between the charge's motion and its magnetic moment, confirming that the magnetic moment is proportional to both the charge and the square of the radius of its orbit.
