SUMMARY
A dielectric sphere containing free charges, when uniformly distributed, generates a net electric field despite being electrically neutral. This occurs because the introduction of free charges creates an electric field both inside and outside the sphere. The distinction between free charges, which are added to the dielectric, and bound charges, which are inherent to the dielectric material, is crucial for understanding this phenomenon. The discussion clarifies that free charges are not present in the dielectric until introduced, while bound charges exist naturally within the material.
