Transformer.Full-text restricted to subscribers or individual document purchasers.Electromagnetics describes the interaction between electric charges, electric currents, magnetic moments, and electromagnetic fields. An electromagnetic field can be static, slowly changing, or form waves. An in-depth knowledge of electromagnetism will be essential to understand the character of light which is an electromagnetic wave and obey the laws of optics. This volume presents a collection of problems in electromagnetics covering basics and the varied areas of applications of electromagnetic principles.Pradeep Kumar Sharma is a well-known physics author and educator in India. He served in many premier institutes like Brilliant Tutorials, (Chennai), FIIT-JEE Ltd (New Delhi), Narayana Group (Andhra and Telangana) etc. He has been associating as a research scholar of physics education, nanoscience, management and metaphysics in some Indian and foreign universities such as Oxford University, Strathclyde University, Indian Institute of Technology, Patna, Sofia University etc. He is actively involved with a team of top-notch educators, to design a new method of interactive education called Active Teaching and Active Learning (ATAL) that will make the things easy for an average student to learn physics.Also available in print.Mode of access: World Wide Web.System requirements: Adobe Acrobat Reader, EPUB reader, or Kindle reader.Title from PDF title page (viewed on October 1, 2025).
