Pedagogical study of the image of a magnetic dipole in front of a superconducting sphere
Hemansh Alkesh Shah, Kolahal Bhattacharya
The method of images to solve certain electrostatic boundary-value problems is taught worldwide in undergraduate-level physics courses. Though it is also possible to employ this te…
Unexplored aspects of a variational principle in electrostatics
Kolahal Bhattacharya, Debapriyo Syam
The electrostatic field magnitude can play a role in a variational principle similar to the role of the index of refraction in geometrical optics, allowing the determination of the…
On the Dependence of Charge Density on Surface Curvature of an Isolated Conductor
Kolahal Bhattacharya
A study of the relation between the electrostatic charge density at a point on a conducting surface and the curvature of the surface (at that point) is presented. Two major scienti…
A Novel Variational Principle in Electrostatics and its Consequences
Kolahal Bhattacharya
We propose a novel variational principle in electrostatics and show that one can derive mirror equation in the context of image problem starting from this principle. The correspond…
Analogy of the grounded conducting sphere image problem with mirror optics
Kolahal Bhattacharya
We show that in the grounded conducting sphere image problem, all the necessary information about the image charge can be found from a mirror equation and a magnification formula.…
