Physics for IGCSE & O level - Magnets And Currents (Section 11 - No. 43)
Which factors can increase the turning effect on the coil in a simple generator?
Increasing the number of turns on the coil.
Using a stronger magnet.
Increasing the area of the coil.
Reducing the current flow.
Explication
The turning effect is proportional to the number of turns, the current, and the area of the coil and the strength of the magnetic field.
