Uses Of The Generator Effect (ht Only) (GCSE Physics)

Which action will increase the output voltage of a simple generator for the same magnet and coil geometry?

Which application uses the generator effect on a tiny scale to sense motion or vibration by producing an electrical signal from movement in a magnetic field?

A detector coil placed near a moving metal object can produce an output because eddy currents are induced. These eddy currents are a consequence of which effect?

A hand-cranked torch flashlight that lights an LED when you crank it uses the generator effect to produce current. Which property of the generator mainly determines the voltage produced for a given crank speed?

How does increasing the number of magnetic poles on a generator rotor affect the frequency of the output voltage for a fixed rotor speed?

Why is a commutator used in a DC bicycle dynamo (if it were made to produce DC) instead of slip rings?

Which of the following is an application of the generator effect in household technology?

Why does increasing the number of turns on the coil in a generator increase the generated voltage?

Which of the following best describes a practical way to increase the power output of a wind turbine’s generator at a given wind speed?

Which part of an AC generator determines whether the output is alternating rather than direct current?

Which of the following best explains why a faster rotation of the turbine in a power station gives a higher electrical output?
