By Prof. Samudra Roy   |   IIT Kharagpur
Learners enrolled: 820
ABOUT THE COURSE:
The course offers a profound understanding of classical electrodynamics where all the problems are solved with mathematical rigor. This self-contained course begins with useful mathematical preliminaries where the students will learn from scratch the mathematical techniques used in electrodynamics. The concepts and physics of electro and magnetostatic are developed gradually with appropriate examples and mathematical problems. Finally the students will learn the development and consequences of Maxwell’s equations that govern the laws of electrodynamics.

Instructor bio

Prof. Samudra Roy

IIT Kharagpur
I did my PhD from CGCRI (a CSIR Lab) in 2009 and carried out my post-doctoral research from Hokkaido University, Japan and Max Planck Institute, Germany during 2009-2013. In 2013, I joined in the Physics Department, IIT-Kharagpur as an assistant professor and also associated with the Center for Theoretical Studies-IIT Kharagpur. My research field is nonlinear photonics.

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.
The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).
Date and Time of Exams: 30 October 2022 Morning session 9am to 12 noon; Afternoon Session 2pm to 5pm.
Registration url: Announcements will be made when the registration form is open for registrations.
The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.
Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Kharagpur. It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.

Once again, thanks for your interest in our online courses and certification. Happy learning.
