Al-Huda Science Academy has designed Class 12 MCQs Physics Chapter 15 Electromagnetic Induction for board, MdCat and ECAT preparation. These MCQs help students to prepare for their entry test papers.
Chapter 15 Electromagnetic Induction includes topics:
- Induced emf and Induced current
- Motional emf
- Faraday’s law of electromagnetic induction
- Lenz’s law and direction of induced emf
- Mutual Induction
- Self Induction
- Energy stored in an inductor
- Alternating Current Generator
