Why this course?


This course is designed to have  detail understanding about magnet, electromagnet & electricity.  This is very essential course for electrical engineering students.  Proper understanding of magnet and electromagnetism will help for  further understanding working of major elector-mechanical devices.  Course contents includes part of syllabus of first year basic  engineering course offers in almost all universities like GTU, IITs,  RTU, as "Basic Electrical Engineering" or "Element of Electrical  Engineering" or under similar title.

Magnetic flux plays an  important role in energy conversion process either form electrical to  mechanical or mechanical to electrical. It is very important to have  clear understanding of electromagnetism and its role in various  applications. Without clear understanding about electromagnetism, it is  not possible understand electric motor, generators, wireless power  transfer, wireless chargers, or induction heating like advanced  applications. So iif someone is struggling in basic concept of  electrical engineering it is advised to go through this course.

This course will be updated continuously for new applications, tutorials and quiz.
