2. Lenz's law is a consequence of the law of conservation of
3. The north pole of a bar magnet is rapidly introduced into a solenoid at one end (say A). Which of the following statements correctly depicts the phenomenon taking place?
4. Direction of current induced in a wire moving in a magnetic field is found using
5. Two identical coaxial coils P and Q carrying equal amount of current in the same direction are brought nearer. The current in
