2nd year physics, Chapter 15: Electromagnetic induction – Exercise questions; (MARKS GUARANTEED)

Hi 2nd year physics students take full marks in FSC part 2 Physics This lecture is on chapter 15 Exercise question and answers. These answers are easy conceptual and effective. Every question and answer is explained in detail. This lecture is for students of FSC physics from Punjab text book board. These are the questions which are covered in the video from 15.1 to 15.10. These are the questions. 15.1: Does the induced emf in a circuit depend on the resistance of the circuit? Does the induced current depends on the resistance of the circuit? 15.2: A square loop of wire is moving through a uniform magnetic field. The normal to the loop is oriented parallel to the magnetic field. Is emf induced in the square loop? 15.3: A light metallic ring is released from above into a vertical bar magnet. Viewed from above, does the current flow clockwise or anticlockwise in the ring? 15.5: Does the induced current always act to decrease the magnetic flux through a circuit? 15.8: How would you position a flat loop of wire in a changing magnetic field so that no emf is induced in the loop? 15.9: In a certain region the earth’s magnetic field points vertically down. When a plane flies due north which wing tip is positively charged? 15.10: Show that 𝜀 and △Ø/△t have the same units. For complete answers watch the complete video.
