Question 11 answer needed

Answer 1

1. Deflection in magnetic compass indicates the generation of electricity I.e. electricity is passed.
2. the bulb does not glow in figure A as it is a non conducting solution which does not allow electricity to pass.
3. increase in number of turns will increase the magnetic feild produced. So, there will be more deflection.
4. If number of cells will increase, more current will be passed and more deflection.
