CAN SOMEONE HELP WITH QUESTION 6 AND 7 ONLY?

1. Explore the link given below to understand the Law of Electromagnetic Induction. Faraday's Law 1.1.23
2. Write down the list of equipment you are using to perform the experiment.
3. Write down your qualitative observation of the blub's brightness depending upon the speed of the magnet through the coil. Do you observe anything interesting?
4. Use another coil with a different number of turns and observe the brightness of the bulb while you are moving the magnet with roughly the same speed. What can you conclude from this?
5. Flip the magnetic poles and perform the above experiment. What is the change in the voltmeter? Can you say something about the direction of the current flowing through the circuit depending upon the magnetic field direction?
6. Finally, given that the cross-sectional area of the coil is A, can you think of a mathematical formula which will relate the emf (voltage detected by the voltmeter) with all the variable quantities you explored?
7. One question still remains puzzling: Why the emf is called an induced emf?
