1Is it possible to generate an electric current from a conducting wire placed in a magnetic field, just the way a magnetic field is developed around the wire when an electric current passes through it?
2What is the difference between the new observation and the previous observation when the bar magnet is quickly moved in and out of the solenoid?
3Define electromagnetic induction.
4What is magnetic flux? How does it change when a magnet is brought towards a coil?
5State Faraday's law of electromagnetic induction.
6A strong magnet is placed inside a coil connected to a galvanometer and left there. Why does the needle not move?
7Name the energy conversion that takes place in electromagnetic induction and explain where the energy comes from.
8What is the working principle of a generator? How can the e.m.f. produced by it be increased?
9Why does increasing the number of turns in a coil increase the induced voltage?
10How long does an induced e.m.f. last? Explain with the example of a rotating coil.
