Whether you are struggling with Poisson's equation or the method of images, our solved assignment provides you with the clarity and confidence you need to score high marks this year.
MPH 003 Assignment Questions
- A uniformly charged solid cylinder of radius a and length L carries a total charge Q. Assuming the observation point lies at a distance x from the centre of the cylinder along its axis and that $L>>a$ derive an expression for the electric field on the axis of the cylinder. Discuss the limiting case when $x>>L$.
- a) Starting from Coulomb's law, derive Gauss's law in differential form. b) Obtain Poisson's equation for electrostatics using the result derived in (a) above. Write down the general solution of Poisson's equation and explain its physical significance for a given charge distribution.
- An infinite plane conducting surface is held at zero potential. A point charge q is placed at a distance d above the plane. Using the method of images, a) determine the electrostatic potential in the region above the plane, b) calculate the force experienced by the charge q.
- Define the electric displacement vector D. Starting from Maxwell's equations, deduce Gauss's law in dielectric media. Explain the physical significance of bound and free charges.
- Obtain an expression for the magnetic vector potential, $\overline{A}$ due to a circular current loop of radius a carrying steady current I, at a point on its axis at distance x from the centre. Discuss the limiting case for $x>>a$.
- a) Derive an expression for the magnetic moment associated with orbital motion of an electron in an atom. b) Define and explain the gyromagnetic ratio and LandΓ© g-factor, stating their physical importance.

FAQs
Is MPH 003 difficult?
Electromagnetic Theory is often considered one of the more challenging subjects in the MSCPH programme because it requires a very strong grasp of vector calculus and abstract physics concepts. Many students find the derivations for things like the magnetic vector potential or Poissonβs equation quite intimidating. However, it isn't "impossible" if you have the right guidance. Our solved assignment breaks these complex ideas down into simple steps that make sense. Instead of getting lost in a sea of equations, we explain the "why" behind each step, which helps you actually learn the material while completing your work.
What are the passing marks for this assignment?
According to the official IGNOU assignment booklet for this course, the total marks allocated for this tutor-marked assignment are 50. To successfully pass this specific component of your continuous evaluation, you need to score a minimum of 20 marks. While 20 is the passing limit, we always recommend aiming much higher because this assignment carries a 30 per cent weightage in your final overall grade for the course. Using a well-structured and accurate solution like ours can help you secure a much higher score than just the bare minimum.
How should I format my answer sheet for submission?
IGNOU is very strict about formatting, and you must write specific details on the top of your first page, including your Course Code, Enrollment Number, and Study Centre. You should use foolscap size paper and ensure you leave a 4 cm margin on the left, top, and bottom of each sheet. It is also highly recommended that you keep a photocopy of your completed assignment before submitting it to your Study Centre, just in case there are any issues during the evaluation process at the university.
Can I submit this assignment for the 2027 session?
No, this specific assignment booklet is only valid from 1st January 2026 to 31st December 2026. If you are unable to submit it by the end of December 2026 or if you do not pass, you will be required to get the fresh assignment booklet for the year 2027 and complete those new questions instead. It is always best to stay updated with the current year's booklet to ensure your marks are processed correctly. Our PDF is specifically designed for the 2026 session to keep you on the right track.
Are the diagrams included in the solved PDF?
Yes, we understand that Physics is incomplete without proper visual representation. For questions involving charged cylinders, point charges above conducting planes, or circular current loops, we have included clear and neat diagrams. These illustrations are designed to be easy for you to replicate in your handwritten submission. A well-drawn diagram not only helps the evaluator understand your logic but also significantly increases your chances of getting full marks for that particular question. We make sure every technical detail is visually supported.
We offer a range of academic resources to support your IGNOU journey. Whether you need a Solved Assignment PDF to save time, IGNOU Guess Papers to ace your upcoming exams, or Previous Year Solved Question Papers to understand the paper pattern, we have it all. If you prefer the personal touch, we also provide Handwritten Assignments in both scanned PDF and hard copy formats, delivered right to your doorstep.
