i) Anticlockwise direction ;
ii) A current flows in the coil a magnetic field is created around it;
- Interaction between the magnetic field due to current and that due to the permanent magnet creates equal and
opposite forces on the coil making it to turn;
- A ensures that current in the coil is maintained in one direction
- P conducts current to Q through the coil and out of Q ;
iii) Increase the number of cells ;
