3 major components of dynamo

Question 1

It is made of coiled copper windings which rotate inside the magnetic field made by the stator. When the windings move, they cut through the lines of magnetic field. this creates pulses of electric power

Answer 1

the armature

Question 2

A fixed structure that makes magnetic field, you can do this in a small dynamo using a permanent magnet. large dynamos require an electromagnet.

Answer 2

The stator

Question 3

this is needed to produce direct current. Since the rotating armature in a dynamo reverses current each half turn, so the commutator is a rotary switch that disconnects the power during the reversed current part of the cycle

Answer 3

the commutator
