How a dynamo works
In short: A dynamo is an electrical generator that creates direct current using self-powering electromagnets and a mechanical commutator.
1. Dynamos are self-starting by using residual magnetic field left in the iron cores of the electromagnets. 2. The dynamo principle refers to direct current generators which use exclusively the self-excitation principle to generate DC power. 3. A dynamo is an electrical generator that creates direct current using a commutator. 4. Dynamos were the first practical electrical generators capable of delivering power for industry.
