TL;DR

This paper investigates how mass, charge, and rotation influence frame dragging in charged rotating bodies, revealing a periodic variation with azimuthal angle and maxima at specific angles.

Contribution

It introduces a combined analysis of mass, charge, and rotation effects on frame dragging, highlighting the periodic nature with respect to azimuthal angle.

Findings

Frame dragging varies periodically with azimuthal angle.

Maximum frame dragging occurs at φ=π/2.

Minimum frame dragging occurs at φ=3π/2.

Abstract

In the present paper, we have considered the three parameters: mass, charge and rotation to discuss their combined effect on frame dragging for a charged rotating body. If we consider the ray of light which is emitted radially outward from a rotating body then the frame dragging shows a periodic nature with respect to coordinate $\phi$ (azimuthal angle). It has been found that the value of frame dragging obtains a maximum at, $ \phi =\frac{\pi}{2}$ and a minimum at $ \phi =\frac{3 \pi}{2}$.
