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

Which device produces an electrical voltage by rotating a coil in a magnetic field and so uses the generator effect?

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

Which vehicle technology uses the generator effect to recover kinetic energy and convert it back into electrical energy during braking?

What is the primary reason that large-scale electricity generation uses rotating generators rather than static induction coils?

A moving-coil microphone converts sound-pressure variations into an electrical signal by which process?

Which device converts mechanical energy to electrical energy using the generator effect and then supplies alternating current directly to a power grid?

Which component in a power station converts the mechanical rotation of a turbine into electrical energy by the generator effect?

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

What change will increase the induced emf in a coil according to Faraday’s law?

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?

Why does increasing the magnetic field strength in a generator increase the induced emf for a given rate of rotation?
